· JVASP-62801· Co2B2O5

Co₂B₂O₅ is a cobalt borate ceramic compound combining cobalt oxide with boric oxide in a crystalline phase. This material belongs to the borate ceramic family and is primarily encountered in research and specialized industrial contexts rather than high-volume commodity applications. Its notable characteristics—including good mechanical rigidity and moderate density—make it of interest for high-temperature applications, glass science, and corrosion-resistant coatings where cobalt-bearing ceramics provide both functional and aesthetic properties.

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.
