· JVASP-10115· CdAs

Cadmium arsenide (CdAs) is a binary compound semiconductor ceramic combining cadmium and arsenic elements. It belongs to the II-VI semiconductor family and is primarily of research and specialized optoelectronic interest rather than a commodity engineering material. CdAs has been investigated for infrared detection, photovoltaic applications, and high-frequency electronic devices, though it remains less developed than related compounds like CdTe or GaAs due to toxicity concerns with cadmium and processing challenges.

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.
