· KAcO3

Potassium acetate trihydrate (KAcO₃·3H₂O) is an inorganic salt ceramic compound combining potassium acetate with bound water molecules, belonging to the family of alkali metal acetate salts. While not a structural ceramic in the traditional sense, it finds use in specialized applications requiring deliquescent or hygroscopic properties, thermal energy storage systems, and laboratory settings where its solubility and phase-change characteristics are valuable. Compared to conventional ceramics, KAcO₃ is notable for its reversible hydration behavior and relatively low melting point, making it better suited for thermal regulation and chemical processes than load-bearing 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.
