What is Boric Acid flake?
Boric acid is also called "positive boric acid".It is made by the reaction of natural borax (sodium borate) with acid.The chemical formula is H3BO3.Molecular weight 61.83.White triclinic axial plane scales with glossy crystals.The relative density is 1.43514, and the refractive index is 1.337, 1.461 and 1.462.Soluble in water, ethanol Chemicalbook and glycerin.The aqueous solution is acidic and is a weak monoacid (Ka=6×10-10).In water solubility increases with increasing temperature.It can be prepared by adding hydrochloric acid or sulfuric acid to borax solution, or by separating borite from hydrochloric acid. application & functionBoric acid is also called "positive boric acid".It is widely used in the production of borate, sodium silicate, borate ester, optical glass, enamels, paints, pigments, cosmetics, food preservatives, leather finishing, printing and dyeing additives and medicine, also can be used as antiseptic disinfectant, astringent.Used in glass, enamel, ceramics, medicine, metallurgy, leather, dye, pesticide, fertilizer, textile and other industries;Used as chromatographic analysis reagent, also used in the preparation of buffer;It is widely used in glass (optical glass, acid-resistant glass, heat-resistant glass, glass fiber for insulating materials) industry, which can improve the heat-resistant and transparent performance of glass products, improve the mechanical strength and shorten the melting time.In the enamel and ceramics industry, used to enhance the luster and fastness of enamel products, and is also one of the ingredients of glazes and pigments.Used as additive and cosolvent in metallurgical industry, especially boron steel with high hardness and good rolling ductility can replace nickel steel.Boric acid has antiseptic properties and can be used as an antiseptic, such as wood preservatives.It is used in metal welding, leather, photography and other industries, as well as in the manufacture of dyes, heat-resistant and fire-resistant fabrics, artificial gems, capacitors and cosmetics.It can also be used as insecticide and catalyst.Agricultural microelement containing boron fertilizer has fertility effect on many crops and can improve crop quality and yield.
