Cov khoom siv dav siv hauv ceramic sib tsoo log, cov khoom siv aluminium siab, aluminium porcelain pob, muaj kiln, hluav taws xob ceramic, high voltage hluav taws xob porcelain, huv ware, niaj hnub porcelain, nitride alloy thiab ua npuas ncauj ceramics thiab lwm yam lag luam.

Kev hnav tsis kam ntawm Si3N4-SiC cov khoom yog 3.13 npaug ntawm cov hlau hnav-tiv taus (Crl5Mo3), thiab qhov hnyav tsuas yog 1/3 ntawm cov hlau hnav-tiv taus (Crl5Mo3).

Kev tiv thaiv corrosion zoo txo qhov tseem ceeb ntawm Si3N4-SiC thiab calcium carbide thiab alumina hauv ntau cov kev daws teeb meem yog raws li hauv qab no:
