· JVASP-21665· Ca3Si4Ir4

Ca3Si4Ir4 is an intermetallic ceramic compound combining calcium, silicon, and iridium in a structured lattice. This is a research-stage material rather than an established industrial ceramic; it belongs to the family of high-entropy and complex intermetallic systems being investigated for extreme-environment applications. The iridium content makes it intrinsically expensive and limits adoption to specialized aerospace, nuclear, or high-temperature catalytic contexts where conventional ceramics prove insufficient.

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.
