· CaSi2

Calcium silicide (CaSi₂) is an intermetallic ceramic compound that combines calcium and silicon, forming a brittle ceramic material with moderate stiffness. It is primarily used as a deoxidizer and desulfurizer in steel production, where it removes oxygen and sulfur impurities during metallurgical processing; additionally, it finds application in specialty alloy development and as a precursor material in silicon-based ceramic synthesis. Engineers select CaSi₂ for high-temperature metallurgical operations where its chemical reactivity and moderate mechanical properties enable cost-effective purification of molten metals, though its brittle nature limits structural applications compared to tougher ceramic alternatives.

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.
