· JVASP-58322· KLiSO4

Potassium lithium sulfate (KLiSO₄) is an ionic ceramic compound combining alkali and alkaline-earth elements in a sulfate crystal structure. This material is primarily of research and specialized industrial interest, studied for potential applications in solid-state electrolytes, optical materials, and high-temperature ceramics where its dual-alkali composition may offer unique ionic conductivity or thermal properties compared to single-alkali alternatives.

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.
