The chemical structure of borax is quite delicate. The main component of borax is sodium tetraborate, and its chemical formula is $Na_2B_4O_7\ cdot10H_2O $. In the structure of borax, boron atoms exhibit a unique coordination form.
Boron atoms often exist in two coordination environments in the structure. One is that boron atoms are connected to three oxygen atoms to form a $BO_3 $structural unit of a planar triangle. In this structural unit, boron atoms are bonded with a $sp ^ 2 $hybrid orbital, which has a planar geometric configuration.
Second, boron atoms are connected to four oxygen atoms to form a $BO_4 $structural unit of a tetrahedron. The boron atoms in this structural unit are hybridized by $sp ^ 3 $, showing the spatial configuration of tetrahedra.
In the structure of borax crystal, $BO_3 $and $BO_4 $structural units are connected to each other. The $BO_4 $tetrahedron and $BO_3 $triangle form a complex anionic skeleton structure by sharing oxygen atoms. The $Na ^ + $ions are distributed in the gaps of these anionic skeletons, and the electrostatic force combines with the anion to maintain the stability of the entire crystal structure.
And the crystalline water of borax also plays an important role in its structure. These ten crystal waters interact with anions and cations in a specific way, or are connected to the oxygen atoms of anions through hydrogen bonds, or surround cations. The existence of crystalline water not only affects the physical properties of borax crystals, such as the morphology and solubility of the crystal, but also plays a certain role in its chemical properties.
The chemical structure of borax is composed of unique coordinated boron-oxygen structural units, interspersed metal ions and crystal water. This delicate structure endows borax with diverse physical and chemical properties, making it important in many fields.

Borax is an important mineral, and its main physical properties are as follows:
Borax is mostly colorless translucent crystals or white crystalline powder in appearance. This color characteristic makes it easy to distinguish in many scenes. Its crystals often have a regular geometric shape, reflecting the delicate structure of natural materials.
Borax has a relatively small density and light texture. With a light touch, you can feel its fine texture, and because of the density, it shows unique advantages in some application scenarios with specific requirements for weight.
Borax has low hardness, with a Mohs hardness of about 2-2.5. This characteristic makes it easier to be scratched or deformed. Scratch with your fingernails, or leave marks on the surface of borax.
Borax has a certain water solubility and dissolves faster in hot water. When borax is put into hot water, it can be seen that it gradually dissolves, and finally fuses with water to form a uniform solution.
Borax has a melting point of 741 ° C and a boiling point of up to 1575 ° C. In high temperature environments, borax will undergo a physical state transformation. When the temperature rises to the melting point, borax melts from solid to liquid; when it reaches the boiling point, it further gasifies into a gaseous state. This change at high temperature has key applications in metallurgy, glass manufacturing and other fields.
Furthermore, borax crystals have a good luster, similar to glass luster. Under light, they can refract a soft light, adding a unique charm to their appearance.
Due to its various physical properties, borax is widely used in many industries such as chemical industry, medicine, metallurgy, and glass, making it an indispensable raw material.

Borax is a medicinal stone. It has extraordinary uses in many fields.
In the field of medical medicine, borax is quite effective. Ancient physicians often used borax as medicine. Its nature is cold, sweet and salty, and it has the ability to clear away heat, detoxify, reduce swelling and preservative. In the case of swelling and pain in the throat, borax is often emphasized by physicians. It can be combined with various medicines, or taken internally, or used externally, to make the swelling and pain gradually disappear. In case of sores in the mouth, applying borax as a powder can clear away heat and reduce fire, reduce sores and relieve pain. In ophthalmology, if the eyes are red, swollen and painful, and the pterygium climbs the eyes, borax also has the effect of reducing redness and swelling and improving eyesight.
In the art of alchemy, borax also has a place. Alchemists are well aware of the characteristics of borax. When refining medicinal pills, borax can be used as a flux. Because borax can reduce the melting point of certain ores, making it easier for various drugs to fuse and react, it helps to refine ideal medicinal pills. During the process of alchemy, it participates in many complex chemical changes, which affect the quality and efficacy of medicinal pills.
As for the ceramic firing industry, borax is also indispensable. Adding an appropriate amount of borax to the ceramic glaze can change the properties of the glaze. Borax can make the glaze more smooth and delicate, and enhance the gloss and transparency of the glaze. And it can reduce the melting temperature of the glaze, make the firing process smoother, and reduce the generation of defective products. In this way, the ceramic utensils made by firing are more ornamental and practical.
In the printing and dyeing industry, borax also plays a role. When printing and dyeing, borax can be used as a mordant. It can make the dye better adhere to the fabric, enhance the firmness of dyeing, make the dyed color more vivid and lasting, and is not easy to fade, so it is very important in the printing and dyeing process.

The method of making calamine is very particular. The ancient Fang family was quite attentive to this matter, and each had a wonderful method passed on to future generations.
One method is to choose the best calamine and soak it in childlike stools. Childlike, its nature is mild, and it can remove the dryness of calamine. During the ten days of soaking, change the stools every day to ensure that the calamine is moisturized by childlike stools. When the time is full, take out the calamine, wash it with water, and put it on a charcoal fire to calcine. When calcining, the heat must be precisely controlled. If the fire is fierce, the calamine is fragile, and if the fire is small, its properties are difficult to change. Wait until it is red, take it out, and quench it in coptis juice. Coptis chinensis is bitter and cold, which can help calamine clear away heat and reduce fire. Repeatedly calcined and quenched several times until the calamine is crispy and can be stopped.
There is another way to cook calamine with three yellow (Coptis chinensis, Scutellaria baicalensis, yellow cypress). The three yellow are all medicines for clearing away heat and dampness, purging fire and detoxifying. With an appropriate amount of water, fry the three yellow juice, then add calamine, and cook it slowly. The cooking time is about two hours, and the calamine is constantly stirred during this time to evenly heat the calamine and fully absorb the medicinal power of the three yellow. After cooking, take out the calamine, dry it, and fry it in a silver pot. When frying, the firepower should not be too large, just fry until slightly yellow, which can make the medicinal effect of calamine more mellow.
There are also goat brain and calamine co-made. Choose fresh goat brain and mix it with calamine in a certain proportion. The goat brain is soft and adjustable to the stiffness of calamine. After mixing the two well, place them in a porcelain jar, seal the mouth of the jar, bury them three feet underground, and take them out after seven, seven, forty-nine days. At this time, calamine is nourished by the goat brain, its medicinal properties are peaceful and unique, and it has many good effects on diseases such as eye diseases.
All kinds of methods, each has its own advantages and disadvantages, are the crystallization of the wisdom of predecessors, and the medicator should choose carefully according to the needs of the disease.

Viewing the market situation and prospects of zinc borate is actually an important business matter, and it is related to the rise and fall of various industries.
In today's world, all industries are competing for prosperity. In the genus of building materials, zinc borate shows its talents with its ability to prevent fire and flame retardancy. When building residential palaces, it is important to prevent fire. Zinc borate is added to paint and plastic materials. In case of fire, it will turn into a heat insulation film, block flames, and protect people's wealth. Therefore, in the city of construction, its needs are like the flow of rivers, which is endless. And the new regulations show that the stricter the fire protection requirements, the more vast the city of zinc borate will become, like Peng spreading his wings, soaring up.
As for the field of electronic appliances, it should not be underestimated. Today's electrical appliances are all over the universe, and heat dissipation and fire protection are its top priorities. Zinc borate has good properties, which can help electrical appliances dissipate heat, and is fireproof in the early stage, ensuring the stability of the circuit and protecting the integrity of the machine center. With the increasing technology, the quality and quantity of electrical appliances are advancing. Zinc borate is like a boat sailing along the water in this city, and the wind is hanging.
Furthermore, in the industry of rubber and fiber, zinc borate is also a good aid. It can increase the toughness of materials and has the effect of flame retardancy. For rubber, it can be wear-resistant and durable, fireproof and explosion-proof; for fiber, it can make the fabric fire-resistant and protect the body. Nowadays, people seek the goodness of things, and they focus on security and quality. There are more and more people using zinc borate in these two industries. The city is also like a seedling when it rains, and it is booming.
However, the market is changing, and there are thorns. The production of zinc borate is related to the supply of raw materials. If the mountains and rivers change, and the mineral supply is not smooth, the production may be blocked, and the price may be floating. And the dispute between the same industry cannot be ignored. Families compete for profits, or come up with new laws, or reduce their prices, and want to occupy the top of the market. However, if you can improve skills, control the quality of the capital, build the world with integrity, and serve people with quality, the city of zinc borate, although there are waves, can eventually be as stable as Mount Tai, with bright prospects.
