· JVASP-88070· CuB4O7

Copper tetraborate (CuB4O7) is an inorganic ceramic compound combining copper oxide and boric oxide phases, forming a mixed-metal borate system. This material family is primarily investigated for specialized optical, electronic, and thermal applications where copper's redox properties and boron's glass-forming characteristics offer functional advantages. Industrial interest centers on optical coatings, glass additives for specific refractive properties, and potential use in electronic ceramics where copper coordination chemistry provides beneficial electronic structure.

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.
