Silicon Carbide (SiC) Hmoov Txheej txheem cej luam
Silicon carbide (SiC), tseem hu ua carborundum los yog emery, yog ib qho ntawm cov khoom siv dav siv thiab kev lag luam. SiC muaj nyob rau hauv ob hom: dub silicon carbide thiab ntsuab silicon carbide.
Txheej txheem ntau lawm
SiC yog tsim los ntawm melting quartz xuab zeb, roj av coke, los yog thee tar, thiab ntoo chips ntawm qhov kub thiab txias nyob rau hauv lub qhov cub tsis kam. Ntsuab silicon carbide tshwj xeeb yog tsim los ntawm melting zoo silicon dioxide thiab roj av coke, nrog ntsev ntxiv raws li ib tug additive.
Khoom thiab Daim Ntawv Thov
- Hardness:Poob ntawm corundum thiab pob zeb diamond.
- Mechanical Strength:Siab tshaj corundum, nkig, thiab ntse.
-Kev coj ua:Muaj qee yam hluav taws xob thiab thermal conductivity.
Vim tias cov khoom no, SiC yog qhov zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm ntev thiab kev tswj xyuas thermal. Nws yog dav siv hauv kev lag luam xws li abrasives, refractories, thiab semiconductors.
Cov yam ntxwv ntawm Silicon Carbide
1. Tsawg Thermal Expansion:Minimizes kev hloov ntawm qhov loj me nrog qhov kub hloov pauv.
2. High thermal conductivity:Hloov cov cua sov kom zoo.
3. Thermal Stress Resistance:Txo qhov ua tau ntawm thermal stress.
4. Zoo heev Thermal Shock Resistance:Withstands ceev kub hloov.
5. Corrosion Resistance:Durable tiv thaiv kev puas tsuaj.
6. Kev kub siab heev: Ua tau zoo nyob rau hauv qhov chaw txias heev thiab kub.
7. Kub-kub Creep Resistance:Ua kom ruaj khov thiab lub zog ntawm qhov kub thiab txias.
