Karbid krem\u00edka, zl\u00fa\u010denina zlo\u017een\u00e1 z at\u00f3mov krem\u00edka a uhl\u00edka, je pozoruhodn\u00fd keramick\u00fd materi\u00e1l zn\u00e1my svojou v\u00fdnimo\u010dnou tvrdos\u0165ou, vysokou tepelnou vodivos\u0165ou a vynikaj\u00facou odolnos\u0165ou proti opotrebovaniu, kor\u00f3zii a oxid\u00e1cii.
