Boron trioxide - Revolvy

Boron trioxide (or diboron trioxide ) is one of the oxides of boron . It is a white, glassy solid with the formula BO. It is almost always found as the vitreous (amorphous) form; however, it can be crystallized after extensive annealing (that is, under prolonged heat). Glassy boron oxide (g-BO) is thought to be composed of boroxol rings which are six-meered rings composed of alternating 3
