Boric trioxide
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 K at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fractu… WebBoric anhydride (Boron trioxide) Anhydride can be obtained by heating boric acid at temperatures higher than 160oC Reducing boron anhydride in the presence of …
