CAS 1303-86-2 — Boron oxide

Boron oxide (B2O3) is a white, glassy solid used primarily in the manufacture of fiberglass, specialty glasses, and ceramics, as well as a flux in metallurgy and a raw material for boron compounds. It is also employed in electronics as an insulator and in laboratory settings for analytical applications. Boron oxide has a CAS number of 1303-86-2, a molecular weight of 61.833 g/mol, and is stored at ambient conditions. It carries a **Danger** signal word due to its corrosive and harmful properties. Molekula supplies boron oxide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
