· K2WO4

K₂WO₄ (potassium tungstate) is an inorganic ceramic compound belonging to the tungstate family, commonly used as a raw material and functional additive in specialized ceramics and glass systems. It serves primarily in optical applications, thermal management systems, and as a precursor compound in tungsten-based ceramic manufacturing, where its high tungsten content and thermal stability make it valuable for high-temperature and wear-resistant 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.
