· JVASP-134474· CdSiO2

CdSiO₂ is a cadmium silicate ceramic compound combining cadmium oxide and silicon dioxide phases. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, with applications leveraging cadmium's optical and electronic properties in combination with silicate's structural framework. The material appears in optoelectronic device development, photocatalytic research, and specialized glass or ceramic coatings where the cadmium component provides photoactive or optical functionality, though regulatory constraints on cadmium use limit broader commercial adoption compared to alternative silicate ceramics.

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.
