Boron oxides are chemical compounds formed by the combination of boron and oxygen. The most common types include boron trioxide (B2O3) and boron oxide (B2O2). These compounds are typically white, glassy solids that are used in various industrial applications, such as glass manufacturing and ceramics. Boron oxides have unique properties, including low thermal expansion and high chemical resistance. They play a crucial role in the production of borosilicate glass, which is known for its durability and ability to withstand temperature changes. Additionally, boron oxides are used as catalysts in chemical reactions and in the production of certain fertilizers.
