Borax is a common inorganic compound with a unique chemical structure. The main component of borax is sodium tetraborate decahydrate, and its chemical formula is $Na_2B_4O_7 · 10H_2O $.
In terms of its structure, boron atoms exhibit two different coordination forms in the anionic structure of borax. Part of the boron atoms exist in the form of a $BO_3 $planar triangle, in which the boron atoms are connected to three oxygen atoms and distributed in a planar manner. The other part of the boron atoms exists in the form of a $BO_4 $tetrahedron, and the boron atoms are connected to four oxygen atoms to form a tetrahedral configuration.
In the crystal structure of borax, $[B_4O_5 (OH) _4] ^ {2 -} $anions are connected to each other by hydrogen bonds, thus forming a complex network structure. In this network structure, $Na ^ + $ions fill the voids in it, and maintain each other with the anions through electrostatic action. Water molecules also exist in the crystal structure. They combine with anions and cations through hydrogen bonds and other forces, which play an important role in the stability of the crystal and the regularity of the structure.
The chemical structure of borax gives it many special physical and chemical properties. For example, in aqueous solutions, borax can undergo hydrolysis reactions, exhibiting the characteristics of buffer solutions, which can maintain the pH of the solution relatively stable. In addition, borax can melt into glassy substances in high temperature environments, which makes it widely used in metallurgy, glass manufacturing and many other fields. In short, the unique chemical structure of borax lays a solid foundation for its diverse applications.

Borax is an important compound of boron and is also a common borate. From the perspective of "Tiangong Kaiwu", its main physical properties are as follows:
Its color is white, like a powder, and it is often in a fine and scattered state, which is visible to the eye. Borax has a certain solubility and is soluble in water, but its solubility varies with temperature. Generally speaking, when the temperature increases, the amount of dissolved in water increases.
The crystal structure of borax has a specific regularity. Its crystal shape often presents a certain geometric shape, which is caused by the law of atomic arrangement inside it. And borax crystals have a certain luster. Although they are not as shiny as metals, they also have their own unique luster texture.
Furthermore, the hardness of borax is not very high, and it is scratched with hard objects, which is easy to leave traces. Its density is smaller than that of common metals, and when you hold it in your hand, you can feel that its texture is not heavy.
Borax will change accordingly when heated. When heated to a certain extent, it will gradually dehydrate, and then change its physical form. This property is crucial in many process applications.
In practical application scenarios, these physical properties of borax determine its use. For example, due to its solubility and heat change properties, it is widely used in ceramics, glass and other industries, which can help improve the performance of products, such as enhancing the heat resistance of glass.

"Tiangong Kaiwu" has a saying: "All lime is used by fire. After it is formed, it will not be damaged forever when it enters the water. Hundreds of millions of boats, hundreds of millions of walls, choking gaps to prevent prostitution, it is a must."
Calcite-3-calcium phosphate has wonderful uses in many fields.
One is that in the field of construction, lime is widely used. In the past, when building houses and walls, lime was often used as a adhesive. "Tiangong Kaiwu" says, "When used to build walls, the stones were screened out and glued by water. Mixing lime with sand, soil, etc., can enhance the stability of the wall, and it will not fall after years of wind and rain. Nowadays, although new building materials are emerging in an endless stream, lime still has unique value in some traditional building restoration and specific construction scenarios.
Second, in the agricultural field, calcium phosphate can be used as phosphate fertilizer. Although the method of using calcium phosphate as phosphate fertilizer is not detailed in "Tiangong Kaiwu", the book pays more attention to soil fertility and crop nourishment. Calcium phosphate is processed and converted into a form that can be absorbed by plants, which can supplement phosphorus for crops, promote root development, grain fullness, and improve crop yield and quality.
Third, in the industrial field, calcite is widely used. Calcite is an important industrial raw material. In glass manufacturing, it can be used as a flux to reduce the melting point of glass and improve the quality and transparency of glass. In the plastics and rubber industries, it can be used as a filler to enhance the hardness and wear resistance of products.
Calcite-3-calcium phosphate plays an indispensable role in construction, agriculture, industry and other fields, and is sincerely a valuable material resource in the world.

The method of making calamine has been known since ancient times. Calamine has a warm nature and a sweet taste. It has the effect of detoxifying the eyesight and reducing the shade, reducing moisture, relieving itching and astringent sores.
One method is to choose high-quality calamine, wash it with water, and remove its impurities. Put it in a crucible and calcinate it with fierce heat to make it red. After about a stick of incense, take out the crucible and quickly put the calcined calamine into the vinegar liquid. This is the quenching method. The vinegar liquid needs to be in sufficient amount, so that it can be soaked in calamine. After quenching, take out the calamine and dry it. Calcined and quenched several times until the texture of calamine is crispy. After this process, the medicinal properties of calamine can be changed, which is easier for the human body to absorb, and the medicinal effect is more significant.
Another method is to first grind calamine into a fine powder, the finer the better, sift it with silica, and take a very fine powder. Then put the fine powder in a silver pot, add an appropriate amount of childlike dung, and cook it slowly over low heat. The childlike dung needs to be fresh urine for healthy children. When cooking, it needs to be stirred continuously to prevent sticking to the pot. Cook until the childlike dung is almost dry, take out the silver pot, and wait for it to cool naturally. In this way, the processing can be used to nourish yin and reduce fire, cool blood and dissipate blood stasis, and enhance the effect of calamine to clear heat and clear eyes, collect moisture and reduce sores.
There is also a decoction of Coptis chinensis, Phellodendron, etc. to clear away heat and dampness, and to soak calamine. First, place Coptis chinensis and Phellodendron chinensis in a pot in a certain proportion, add water to cook, and take the thick juice. After the thick juice cools, soak the calamine in it for a certain period of time. During the soaking period, it is necessary to stir several times a day to make the calamine fully absorb the concoction. Then take it out, dry it, and then perform subsequent operations such as calcination and quenching. This is because of the properties of various medicines, synergistic effect, so that calamine has better efficacy in detoxification, clearing away heat, and moisture.
