Product Description
Product Application(Boric Acid)
Prepare a buffer. Various borate salts were prepared. Insecticides for black beetles in cockroaches and carpets. It is used as a hemostatic agent and a preservative in medicine.
Used as a pH adjuster, disinfectant, antibacterial preservative, etc.; used in the preparation of borate, borate, optical glass, paint, pigment, boric acid soap, leather finishing agent, printing and dyeing auxiliaries and pharmaceutical disinfection Agents, etc.
Used in capacitor manufacturing and electronic component industry, high purity analytical reagents, medicinal disinfection and antiseptic preparation and processing of exposed photosensitive materials.
Used in glass, enamel, ceramics, medicine, metallurgy, leather, dyes, pesticides, fertilizers, textiles, etc.; used as chromatographic reagents, also used in the preparation of buffers; used in glass (optical glass, acid-resistant glass, resistant) Industrial use of glass fiber for hot glass and insulating materials can improve the heat resistance and transparency of glass products, improve mechanical strength, and shorten melting time. In the enamel and ceramic industry, it is also one of the ingredients of glaze and pigment to enhance the gloss and fastness of enamel products. In the metallurgical industry, additives and cosolvents, especially boron steel, have high hardness and good rolling ductility and can replace nickel steel. Boric acid is antiseptic and can be used as a preservative, such as wood preservation. It is used in the fields of metal welding, leather, photography, and the manufacture of dyes, heat-resistant fireproof fabrics, artificial gemstones, capacitors, and cosmetics. It can also be used as an insecticide and a catalyst. Boron-containing trace element fertilizers in agriculture have fertilizer effects on many crops, which can improve crop quality and increase yield.
Chemical Property
White powdery crystals or three-slanted scaly ribbons with glossy crystals. It has a slippery feel and no odor. Soluble in water, alcohol, glycerin, ethers and essential oils. Odorless. The taste is slightly bitter and sweet. It has a slippery feel when in contact with the skin. There is no change in the exposed air. Can volatilize with water vapor. When heated to 100-105 ° C, one molecule of water is lost to form metaboric acid, which is converted to pyroboric acid by heating for a long time at 104-160 ° C, and an anhydrate is formed at a higher temperature. The pH of the 0.1 mol/L aqueous solution was 5.1. 1 g was soluble in 18 ml of cold water, 4 ml of boiling water, 18 ml of cold ethanol, 6 ml of boiling ethanol and 4 ml of glycerin. Solubility in water increases with the addition of hydrochloric acid, citric acid and tartaric acid. The relative density is 1.4347. The temperature of 184 ° C (decomposition). The boiling point of 300 ° C. The median lethal dose (rat, oral) 5.14G/kG. Irritating. Toxic, death caused by severe oral administration, the minimum amount of death: 640mg/kg for adults, 8.6g/kg for skin, 29mg/kg for intravenous use; 200mg/kg for infants. The maximum allowable concentration in air is 10 mg/m3.
