· Cs2CO3

Cesium carbonate (Cs2CO3) is an inorganic ceramic compound and alkali metal carbonate primarily used in specialized optical, electronic, and catalytic applications. Industrial use is concentrated in photomultiplier tube (PMT) windows, laboratory catalysts for organic synthesis, and as a precursor material in advanced ceramics and solid-state electrochemistry research. Its high refractive index and photoemission properties make it valuable in photodetector systems, while its basicity and thermal stability enable applications in heterogeneous catalysis and materials synthesis where conventional carbonates are unsuitable.

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.
