Boric acid is actually a hydrate of boron oxide(B2O3H2O), which is a white powder crystal o a sealy glossy crystal on a tri-oblique axis , feel soapy if touched,and it is odouless. Soluble in water,alcohol. glycerin, others and esscntial oils, odorless,slightly sour and bitter after taste. Exposure does not change in the air, and can volatilize with water vapor.When heated to 101-105 °C, a molecule of water is lost then form metaboric acid; when heated for a long time at 104-160°C, it is converted into pyroboric acid,and anhydrous is formed at higher temperaturc. The PH of boric acid is 5.1.1g boric acid can be dissolved in18ml cold water,4ml boiling water,18ml cold ethanol, 6ml boiling ethanol and 4ml glyeerol. The solubility in water can be increased with the addition of hy-drochloric acid, citric acid and tartaric acid.Relative density: 1.4347, melting point 184ºC(decomposition), boiling point 300'C.
1.Used in glass, enamel, ceramics, medicine, metallurgy, leather, dye, pesticide, fertilizer, textile and other industries;
2.Used for chromatographic analysis reagent, also used for the preparation of buffering agent;
A large number of glass (optical glass, acid-resistant glass, heat-resistant glass, insulating materials with glass fiber) industry, can improve the heat resistance, transparency of glass products, improve mechanical strength, shorten the melting time.
3.In enamel, ceramic industry, to enhance the luster and fastness of enamel products, is also one of the ingredients of glazes and pigments. Boron steel can be used as additive and cosolvent in metallurgical industry, especially boron steel with high hardness and good rolling ductility, which can replace nickel steel. Boric acid is antiseptic and can be used as a preservative, such as wood. It is used in metal welding, leather, photography and other industries, as well as in the manufacture of dyes, heat and fire resistant fabrics, artificial gems, capacitors and cosmetics.
4.It can also be used as insecticide and catalyst. In agriculture, boron micronutrient fertilizers are effective for many crops and can improve crop quality and yield.
