Thermal conductivity nke brik na -agbanwe agbanwe (Thermal conductivity)

A na-egosipụtakarị conductivity thermal conductivity (thermal conductivity) nke brik refractory, ya bụ, ikike ya ịnyefe ọkụ, na-egosipụtakarị n’ihe gbasara okpomọkụ. Thermal conductivity na-ezo aka ọnụ ọgụgụ nke okpomọkụ gafere site a unit oge na a unit okpomọkụ gradient na usoro nke ike nyefe. The thermal conductivity nke dị iche iche ihe na-adịkarị iche iche. N’ebe okpomọkụ dị n’ime ụlọ, ikuku okpomọkụ nke brik dị iche iche nwere ike ịmalite site na pasent ole na ole ruo ọtụtụ iri (w / (m · ℃)), na ọdịiche dị n’etiti ọnụ ahịa kachasị elu na ọnụ ala dị ala bụ ihe fọrọ nke nta ka ọ bụrụ otu puku ugboro. Ka okpomọkụ na-abawanye, ọdịiche nke thermal conductivity brik dị iche iche na-ebelata, ma ọdịiche ahụ ka dị nnọọ ukwuu. Ka ihe atụ, na 1000 ℃, thermal conductivity nke fechaa silica bụ naanị banyere 0.35W / (m · ℃); ngwaahịa silicon carbide recrystallized dị ihe dị ka 17.5W / (m · ℃); graphite nwere ike ịdị elu dị ka 35W / (m·℃) .
