Morphology
calcium + carbide
The term is a systematic chemical compound name formed by the element 'calcium' + 'carbide' (a carbon-containing compound), so a learner who knows those constituents can infer it refers to a compound of calcium and carbon used in industry. This follows regular, transparent naming patterns in chemistry (element + type of compound) rather than an idiomatic or metaphorical meaning.
Etymology
Calcium carbide is named from its two parts, with calcium a metal and carbide a kind of carbon compound. Picture miners dropping water on a lump of calcium carbide to make 'acetylene' gas for a lamp—this clear image shows why the name fits what the substance does today.
