Daim Ntawv Thov Khoom
Cov raj sapphire siv dav hauv kev lag luam ua tau zoo xws li kev ua cov khoom siv semiconductor, aerospace, optics, thiab chemical engineering. Lawv lub peev xwm tiv taus qhov kub thiab txias heev (txog li 1,600 ° C), ua ke nrog kev tiv thaiv tshuaj lom neeg zoo rau cov kua qaub thiab alkalis, ua rau lawv zoo tagnrho rau cov cub tawg kub thiab cov chaw corrosive. Tsis tas li ntawd, lawv qhov kev pom tseeb zoo dua thoob plaws UV mus rau IR wavelengths ua rau lawv muaj txiaj ntsig zoo hauv cov kab ke optical. Lub raj sapphire lub zog siab thiab thermal conductivity kuj tseem ceeb rau cov ntawv thov uas xav tau kev ruaj khov thiab cua sov dissipation, xws li hauv cov khoom siv hluav taws xob thiab cov tshuab fais fab.
Kev Txheeb Xyuas Tag Nrho
Lub raj sapphire, ua los ntawm 99.999% ntshiab Al₂O₃ ib leeg siv lead ua sapphire, yog cov khoom siv zoo tshaj plaws tsim los siv rau hauv kev lag luam ua tau zoo xws li semiconductors, aerospace, optics, thiab chemical engineering. Nrog qhov nyuaj ntawm 9 ntawm Mohs scale, nws muaj kev tiv thaiv khawb zoo dua thiab lub zog kho tshuab. Nws tuaj yeem ua haujlwm hauv qhov chaw kub heev nrog qhov kub txog li 1,600 ° C, ua rau nws zoo tagnrho rau cov cub tawg kub thiab cov chaw corrosive vim nws cov tshuaj tiv thaiv zoo heev.
Tsis tas li ntawd xwb, lub raj sapphire lub thermal conductivity ntawm 46 W/m·K ua kom muaj kev kub hnyiab zoo, thaum nws lub pob tshab siab thoob plaws UV mus rau IR wavelengths txhawb nqa cov ntawv thov kho qhov muag tseem ceeb. Ua ke nrog nws cov khoom dielectric zoo heev, cov khoom no yog cov kev daws teeb meem zoo rau cov khoom siv hluav taws xob, cov tshuab fais fab, thiab cov khoom siv kho qhov muag. Nrog rau kev ua haujlwm ntev, kev ruaj khov, thiab kev ua tau zoo, cov raj sapphire xa kev ntseeg siab hauv qee qhov chaw lag luam thiab thev naus laus zis uas xav tau tshaj plaws.
