ceramic

· JVASP-25515· KH3F4

KH3F4 is a fluoride-based ceramic compound belonging to the potassium hydrogen fluoride family, characterized by ionic bonding typical of halide ceramics. This material is primarily encountered in specialized chemical and optical applications where fluoride ceramics offer transparency to infrared radiation and chemical inertness that conventional oxides cannot match. KH3F4 is notable for its use in infrared optics, thermal management systems, and corrosive environment applications where its resistance to aqueous and acidic attack provides advantages over silicate-based ceramics.

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.
