Dub silicon carbidethiabntsuab silicon carbidemuaj purities sib txawv thiab siv. Nov yog cov lus qhia ntxaws ntxaws rau cov ntsiab lus hauv qab no:
1. Dub silicon carbide muaj txog 98.5% SiC. Dub silicon carbide muaj zog ntau dua li ntsuab silicon carbide thiab feem ntau yog siv los ua cov ntaub ntawv uas tsis muaj zog tensile, xws li iav, ceramics, pob zeb, cov ntaub ntawv refractory, cam khwb cia hlau thiab non-ferrous hlau. Ntsuab silicon carbide muaj ntau dua 99% SiC thiab muaj cov khoom zoo ntawm tus kheej. Nws feem ntau yog siv los ua cov cemented carbide, titanium alloy thiab optical iav, thiab tseem yog siv rau honing lub tog raj kheej liners thiab zoo sib tsoo ntawm high-speed steel cov cuab yeej.
2. Tsis tas li ntawd, muaj ntau yam tshwj xeeb ntawm silicon carbide, uas yog cubic silicon carbide, tshwj xeeb uas ua rau daj-ntsuab siv lead ua, uas feem ntau yog siv rau hauv kev lag luam xov, xws li kev ua cov bearings, thiab muaj micro-machining zoo. teebmeem.
Silicon carbide muaj ntau lwm yam kev siv dua li cov abrasives vim nws cov khoom ruaj khov, thermal conductivity, tsis tshua muaj thermal expansion coefficient thiab hnav tsis kam. Piv txwv li, los ntawm kev siv cov txheej txheem tshwj xeeb los siv cov hmoov silicon carbide rau sab hauv phab ntsa ntawm lub turbine impeller lossis lub tog raj kheej lub cev, nws tuaj yeem txhim kho nws cov hnav tsis kam thiab ua kom nws lub neej ua haujlwm ntev li 1 txog 2 zaug; cov khoom siv high-grade refractory ua los ntawm nws yog resistant rau thermal shock, me me, lub teeb nyob rau hauv qhov hnyav, siab zog, thiab muaj zog-txuag nyhuv.
Silicon carbide muaj zog hardness, zoo heev thermal conductivity, yog ib tug semiconductor, thiab tuaj yeem tiv taus oxidation ntawm qhov kub thiab txias.
