· JVASP-143669· CaSi3

CaSi₃ (calcium silicide) is an intermetallic ceramic compound belonging to the silicide family, characterized by strong calcium-silicon bonding that imparts high thermal and chemical stability. This material finds application primarily as a deoxidizer and desulfurizer in steel and iron production, where it improves alloy cleanliness and mechanical properties; it is also investigated for use in high-temperature structural applications and as a precursor in advanced ceramic processing due to its potential for thermal resistance and chemical inertness.

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.
