Borax is a salt normally encountered as a hydrated borate of sodium, with the chemical formula Na2H20B4O17. Borax mineral is a crystalline borate mineral that occurs in only a few places worldwide in
Boron trioxide
…trigonal network undergoes a coesite-like transformation to monoclinic β-B2O3 at several gigapascals (9.5 GPa). Boron trioxide is produced by treating borax with sulfuric acid in a fusion furnace. At temperatures above 750 °C, the molten boron oxide layer separates out from sodium sulfate. It is then decanted…
