Calcium silicide (CaSi) is an intermetallic ceramic compound combining calcium and silicon, typically employed as a desulfurizer and deoxidizer in steelmaking and cast iron production. It is valued in metallurgical processing for removing unwanted sulfur and oxygen impurities, improving steel cleanliness and mechanical properties, and is also investigated for potential use in advanced ceramic composites and high-temperature structural applications due to its ceramic character.
