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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
