BO

Boron oxide (B₂O₃) is an inorganic ceramic compound formed primarily from boron and oxygen, typically existing as a glassy or amorphous phase at standard conditions. It is widely used in glass manufacturing—particularly in borosilicate glasses for laboratory and thermal-resistant applications—as well as in enamel coatings, nuclear shielding, and specialized refractory materials where its thermal stability and chemical inertness are advantageous. Engineers select boron oxide-based ceramics for applications requiring low thermal expansion, high temperature tolerance, and chemical durability, making it an alternative to silica-based ceramics in demanding environments.
