calcine
This term is a highly specialized technical verb used almost exclusively in chemistry, metallurgy, and ceramics. It describes a specific thermal process where a material is heated to drive off volatile substances or decompose carbonates without melting the rest of the material. It is distinct from smelting, which involves melting the ore to extract metal.
Because of its narrow scientific application, the word is rarely encountered in general conversation. It carries a neutral, clinical tone and is typically found in laboratory manuals, industrial patents, or academic papers regarding material science.
