Ukumelana nokushisa okuphezulu kokumelana nokumelana nokuqina okuphezulu kwesigubhu sokugaya se-silicon carbide kungenziwa ngokwezifiso

(1) Ukumelana nokushisa okuphezulu, i-coefficient encane yokwanda okushisayo
I-silicon carbide yenziwa emazingeni okushisa aphezulu. Kwenye indawo yokushisa ephezulu, impahla iyadingeka ukuze ibe namandla athile okucubungula, futhi ihlangabezane nokunemba kokucubungula, futhi i-silicon carbide ceramics ingafinyelela la maphuzu amabili. Izinga lokushisa eliphakeme kakhulu le-silicon carbide licishe libe ngu-800 ℃, kanti izinga lokushisa lensimbi lingama-250 ℃ kuphela. Ukubala okunzima, isilinganiso sokunwetshwa kwe-thermal coefficient ye-SIC singu-4.4×10-6/ C ebangeni elingu-25~1400℃. I-coefficient yokwandisa okushisayo ye-SIC incane kakhulu kunaleyo yamanye ama-abrasives nezinto zokushisa eziphezulu. Isibonelo, i-coefficient yokunwetshwa okushisayo kwe-corundum ingaba phezulu njenge-(7~8)× 10-6/℃.

(2) High conductivity ezishisayo
I-high conductivity eshisayo ye-SIC ingenye isici esibalulekile sezakhiwo zayo ezibonakalayo. I-thermal conductivity ye-silicon carbide iphakeme kakhulu kunezinye izinto eziphikisayo nama-abrasives, cishe izikhathi ezi-4 kune-corundum. I-silicon carbide yokwandisa i-thermal coefficient iphansi, i-thermal conductivity ephezulu, okwenza imikhiqizo yayo ibe senkambweni yokushisisa nokupholisa ngaphansi kwengcindezi encane yokushisa, okuphinde kube yimikhiqizo ye-silicon carbide ukumelana nokushaqeka okushisayo kuyisizathu esihle kakhulu.

(3) Ukumelana nokugqwala
I-silicon carbide ngenxa yendawo yayo yokuncibilika (izinga lokushisa lokubola), inertia yamakhemikhali kanye nokumelana nokushaqeka okushisayo kuphezulu, ingasetshenziselwa imikhiqizo ehlukahlukene ye-silicon carbide ceramic, njengemikhiqizo yobumba amathuluzi okugaya isithando somlilo, ipuleti losilingi kanye nesaga, i-zinc encibilikisa mpo yezimboni. Isithando somlilo esine-silicon carbide, i-aluminium electrolytic cell lining, i-crucible, into encane yomlilo.
