Silicon carbide ceramic raj muaj qhov kub thiab txias ruaj khov thiab tuaj yeem tswj hwm nws cov qauv thiab kev ua tau zoo nyob rau hauv qhov chaw kub heev. Nws tuaj yeem tiv taus qhov kub siab txog ntau txhiab degrees Celsius, yog li nws muaj ntau yam kev siv hauv kev siv kub. Tsis tas li ntawd, silicon carbide ceramic raj kuj muaj cov thermal conductivity zoo thiab tuaj yeem ua kom sov tau zoo, ua rau nws ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas thermal thiab cua sov dissipation.
Silicon carbide ceramic tube kuj muaj cov tshuaj lom neeg ruaj khov thiab corrosion kuj. Nws muaj kev tiv thaiv zoo rau ntau cov kua qaub, alkalis thiab lwm yam tshuaj, ua rau nws siv dav hauv cov txheej txheem tshuaj, corrosive ib puag ncig thiab kev kho cov kua qaub. Tsis tas li ntawd, silicon carbide ceramic raj kuj muaj qhov sib npaug ntawm thermal expansion, uas ua rau nws muaj kev ruaj ntseg zoo thaum kub hloov.
Silicon carbide ceramic raj muaj ntau yam kev siv hauv ntau qhov kev lag luam. Nyob rau hauv high-temperature furnaces, cov khoom siv kho cua sov thiab cov burners, silicon carbide ceramic raj tuaj yeem siv los ua cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv thermal rwb thaiv tsev. Hauv kev lag luam tshuaj, nws tuaj yeem siv rau cov kav dej, cov reactors thiab cov tank cia rau cov xov xwm corrosive. Tsis tas li ntawd, silicon carbide ceramic raj kuj tau siv dav hauv kev tsim khoom semiconductor, kev lag luam hnub ci, khoom siv hluav taws xob thiab aerospace.
Cov duab thiab qhov loj tuaj yeem ua raws li qhov xav tau
Siab hardness (HV10): 22.2 (Gpa)
Tsawg ceev (3.10-3.20 g / cm³)
Thaum kub txog 1400 ℃, SiC tuaj yeem tuav nws lub zog
Vim tias nws cov tshuaj lom neeg thiab lub cev ruaj khov, SiC muaj zog hardness thiab corrosion kuj.
