Morphology

silicon + carbide

The term is a straightforward chemical compound name formed compositionally from 'silicon' + 'carbide', so a learner who knows both nouns can infer it denotes a carbide containing silicon (a silicon–carbon material). While detailed technical properties (hardness, color, semiconductor uses) are specialist knowledge, the basic meaning as a material compound is transparently derivable from the constituents.

Etymology

Silicon carbide is a name that tells you what it is: silicon and carbon joined to make tiny blue-black crystals that look like very hard, sharp stones. Picture those sharp crystals — that's why the material is used to cut and grind things and to resist high heat in electronics.
