· JVASP-52867· KPH2O4

KPH2O4 is a potassium phosphate ceramic compound belonging to the family of inorganic phosphate materials. This material is primarily used in specialized applications requiring chemical stability and thermal properties inherent to phosphate ceramics, including laboratory equipment, catalyst supports, and ion-exchange systems. Phosphate ceramics like KPH2O4 are valued for their corrosion resistance in acidic environments and low thermal conductivity, making them alternatives to silicate ceramics in niche applications where conventional oxides are unsuitable.

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.
