· JVASP-133128· KPO4

KPO₄ (potassium phosphate) is an inorganic ceramic compound belonging to the phosphate ceramic family, characterized by ionic bonding between potassium cations and phosphate anions. It is primarily used in specialized industrial applications including phosphate-bonded refractories, dental cements, and bioactive ceramic systems where chemical stability and biocompatibility are required. KPO₄ is notable for its relatively low density compared to many oxide ceramics and its potential as a binder phase in composite refractories, though it is less commonly specified than other phosphate ceramics like aluminum phosphate (AlPO₄) in high-temperature 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.
