Khoom siv
Sapphire raj yog dav siv nyob rau hauv high-kev ua tau zoo industries xws li semiconductor ua, aerospace, optics, thiab chemical engineering. Lawv muaj peev xwm tiv taus qhov kub thiab txias (txog 1,600 ° C), ua ke nrog cov tshuaj tiv thaiv tshwj xeeb rau cov kua qaub thiab alkalis, ua rau lawv zoo tagnrho rau cov cua kub kub thiab qhov chaw corrosive. Tsis tas li ntawd, lawv qhov kev pom zoo tshaj plaws thoob plaws UV rau IR wavelengths ua rau lawv muaj txiaj ntsig hauv cov tshuab kho qhov muag. Lub raj sapphire lub siab mechanical zog thiab thermal conductivity kuj tseem ceeb heev rau cov ntawv thov uas yuav tsum tau ua kom muaj zog thiab cua sov, xws li hauv hluav taws xob thiab hluav taws xob.
Zuag qhia tag nrho
Lub raj sapphire, ua los ntawm 99.999% ntshiab Al₂O₃ ib leeg siv lead ua sapphire, yog ib qho khoom tshwj xeeb tsim los siv rau hauv kev lag luam ua haujlwm siab xws li semiconductors, aerospace, optics, thiab chemical engineering. Nrog lub hardness ntawm 9 ntawm Mohs nplai, nws muaj superior khawb kuj thiab txhua yam muaj zog. Nws tuaj yeem ua haujlwm hauv qhov chaw huab cua nrog qhov kub txog li 1,600 ° C, ua rau nws zoo tagnrho rau cov cua kub kub thiab cov chaw corrosive vim nws cov tshuaj tiv thaiv zoo heev.
Tsis tas li ntawd, lub raj sapphire thermal conductivity ntawm 46 W / m·K ua kom cov cua sov ua kom zoo, thaum nws cov pob tshab siab thoob plaws UV rau IR wavelengths txhawb kev siv kho qhov muag tseem ceeb. Ua ke nrog nws cov khoom zoo heev dielectric, cov khoom no yog ib qho kev daws teeb meem zoo rau cov khoom siv hluav taws xob, lub zog hluav taws xob, thiab optics. Nrog rau kev ua haujlwm siab, kev ruaj ntseg, thiab kev ua haujlwm, sapphire hlab xa kev ntseeg siab hauv qee qhov kev xav tau tshaj plaws hauv kev lag luam thiab kev lag luam.
