· KBO3

KBO₃ (potassium triborate) is an inorganic ceramic compound belonging to the borate family, composed of potassium and boron oxide. It is primarily used in optical and photonic applications, including nonlinear optics for frequency conversion and laser systems, as well as in glass and enamel formulations where it acts as a flux and glass-forming agent. The material is valued for its transparency in the UV-visible range and its nonlinear optical properties, making it an alternative to other borate crystals in specialized photonics applications; however, it remains less common than boron-based ceramics like borosilicate glass in mainstream industrial use.

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.
