XUSUSIYATLARI
Silicon karbid elektr boshq Olovni eritish dan kvars qumi, neft koks (yoki CHAR), talaş qilingan. Tabiatda ham kamdan-kam kremniy karbid mineral moissanite bor. Shuningdek, Moissanite deb nomlanuvchi Silicon karbid. zamonaviy C, N, B va yuqori texnologiyali boshqa nodavlat oksidi, refrakter materiallari, kremniy karbid eng keng tarqalgan va eng tejamkor hisoblanadi. Emery yoki qiyin eriydigan qum, deb atash mumkin. Silicon karbid kvars qumi, neft koks (yoki ko'mir smola), yog'och bilan yuqori harorat qarshilik o'choq eritish va boshqa xom ashyo (yashil kremniy karbid tuz ishlab chiqarishni ko'paytirish kerak). Silikon karbür hozirgi Xitoyning sanoat mahsulotlari ishlab chiqarish qora kremniy karbid va yashil kremniy karbid ikki xil bo'linadi, 3.25 uchun 3.20 uchun buxgalteriya, olti burchakli kristallar bor, microhardness 2840 ~ 3320kg / mm2
