Boron oxide (B₂O₃) is an inorganic ceramic material composed of boron and oxygen, typically formed as a glassy or crystalline solid with exceptional thermal and chemical stability. It is primarily used in glass formulations, borosilicate ceramics, and specialized coatings where high temperature resistance and chemical inertness are required. Engineers select boron oxide-based materials for applications demanding superior thermal shock resistance, low thermal expansion, and resistance to corrosive environments—properties that make it particularly valuable in laboratory glassware, industrial furnace linings, and protective coatings for high-temperature components.

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.
