Jan 17, 2020u00a0u00b7 boron trioxide (or diboron trioxide) is one of the oxides of boron. it is a white, glassy solid with the formula b2o3. it is almost always found as the vitreous (amorphous) form; however, it can be crystallized after extensive annealing (that is, under prolonged heat). Boron oxide (anydrous boric acid) is a colorless, odorless, hygroscopic, solid, white and glassy product available in two granular powder forms: glassy and porous. by virtue of its production method and its inherent nature, the glassy form is almost vitreous.
