K2SO4
ceramic· K2SO4
Potassium sulfate (K₂SO₄) is an inorganic salt ceramic compound commonly produced as a white crystalline solid, primarily valued for its ionic conductivity and thermal stability. It is widely used in fertilizer production (potash), glass manufacturing, and specialty chemical applications, where its solubility, hygroscopicity, and chemical reactivity make it preferable to alternatives like sodium sulfate in moisture-sensitive formulations. In advanced applications, K₂SO₄ serves as an electrolyte material and thermal energy storage medium, and has been investigated for use in molten salt systems for concentrated solar power and high-temperature electrochemical cells.

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.
