Boric Acid (H₃BO₃)

CAS/TSCA Number 10043-35-3

Description: Boric acid, also known as orthoboric acid, is a free-flowing, white, crystalline salt. Boron, the key element in boric acid, is an essential micronutrient and is present in all foods, particularly fruits, vegetables, grains, and nuts. The average person consumes between one to three milligrams each day as part of a normal healthy diet. Boron occurs naturally in air, water, and soil. Boric acid is a mild acid often used as an antiseptic, insecticide, and flame retardant. Despite its use as an insecticide, the LD50 toxicology of boric acid is about the same as table salt. When used as an insecticide, the product must carry an EPA (Environmental Protection Agency) registration number. Boric acid is available from InCide® Technologies in both powder and granular technical grades packaged in 50 and 100 pound multiwall paper bags. Granular boric acid is also available in 2,000 pound tote containers. InCide® Technologies grinds powder boric acid the day prior to shipment to assure the freshest material to be found.

Properties: Boric acid has a specific gravity of 1.51 and is soluble in water (5.46% at 770F/250C). When heated above 1700C it dehydrates, forming metaboric acid HBO₂. Metaboric acid is slightly soluble in water and melts at about 2360C. When heated above 3000C further decomposition takes place forming tetraboric acid or pyroboric acid H₂B₄O₇.

Stability: Boric acid is stable and does not change under normal storage conditions. Wide fluctuations in temperature and humidity can result in caking. Care should therefore be taken to avoid such fluctuations during storage of the product.
