Ihe na-emetụta thermal conductivity (thermal conductivity) nke brik na -agbanwe agbanwe

The thermal conductivity nke refractory brik na-abụghị nanị na-emetụta okpomọkụ, ma na-metụtara chiri anya ya chemical ịnweta mejupụtara na nhazi Ọdịdị. Mgbe brik refractory mejupụtara kristal, ihe ndị dị na kristal nwere mmetụta dị ukwuu na conductivity thermal. Dị ka anyị niile maara, thermal conductivity nke inorganic na-abụghị ọla bụ n’ozuzu nnọọ ala karịa nke ọla. Nke a bụ n’ihi na ihe inorganic na-abụghị ọla, n’adịghị ka ọla nwere agbụ ọla, nwere obere eletrọn n’efu. N’ime ihe a, okpomọkụ conduction nke free electrons na-akpa oke oke, na-tumadi kpebisiri ike site n’ókè nke deviation nke lattice vibration si resonance. Ka ukwuu nke ndiiche si resonance, nta nke thermal conductivity. Ogo nke lattice vibration deviation na-abawanye na-abawanye nke dị iche na molar uka nke mejupụtara bekee, otú thermal conductivity nke elemental umi bụ ndị kasị ibu (thermal conductivity nke graphite bụ ibu).
