Boric acid

CAS number : 11113-50-1

Molecular weight :61.83

Molecular formula/chemical symbol :H3BO3

Description :

Apearances: White crystalline powder or three oblique axial plane scaly shiny crystals, creamy feel, no odor. Specific gravity of 1.435 (15 ? C). Soluble in water, alcohol, glycerin, ethers and essential oils, a weak acid solution. Increasing the solubility of boric acid in water with increasing temperature, and can be volatile with water vapor; inorganic acid solubility than in the solubility in water is small. Was heated to 70 ~ 100 ℃ gradually dehydration metaborate, pyroborate is generated when the 150 to 160 ? C, 300 ° C is generated when the boric anhydride (B2O3).

USES :

Used extensively for the glass (optical glass, acid-resistant glass, heat-resistant glass, an insulating material with glass fibers) industry, can improve the heat of the glass article, the transparent performance, improved mechanical strength, shortening of the melting time. In enamel, ceramics, enamel gloss and fastness to enhance, but also one of the ingredients of glaze and pigment.

2 as an additive in the metallurgical industry, solubilizers, especially boron steel having a high hardness and good rolling ductility, can be used instead of nickel steel. Boric acid corrosion resistance, can be used as preservatives, such as a wood preservative. It is used in metal welding, leather, photographic and other industries, as well as dyes, heat-resistant fireproof fabric, artificial gems, capacitors, cosmetics manufacturing. Can also be used as insecticides and catalyst used.

3. Agriculture boron trace element fertilizer, fertilizer effect on many crops, enhance crop quality and increase production. Boric acid is also one of the basic raw material for the production of other borides, boron compounds produced by it is widely used in national defense and other industrial sectors and research institutes.
