· Ca2B2O5

Calcium borate (Ca₂B₂O₅) is an inorganic ceramic compound composed of calcium, boron, and oxygen, belonging to the borate ceramic family. It is primarily used in specialty glass and ceramic formulations, particularly in borosilicate glass production, thermal insulation materials, and advanced ceramics where boron's glass-forming properties enhance durability and chemical resistance. Engineers select calcium borate systems for applications requiring thermal shock resistance, low thermal expansion, and improved mechanical stability compared to pure oxide ceramics, making it valuable in high-temperature industrial environments and composite reinforcement applications.

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.
