EFG pob tshab sapphire raj loj sab nraud Txoj kab uas hla Kub thiab siab tsis kam

Kev Piav Qhia Luv:

Lub raj sapphire yog ib lub cylindrical qauv ua los ntawm sapphire, uas yog ntau yam ntawm cov pob zeb corundum. Cov raj sapphire paub txog lawv qhov nyuaj tshwj xeeb, kev ua kom sov siab, thiab cov khoom siv kho qhov muag zoo heev. Lawv feem ntau siv rau hauv cov ntawv thov kub thiab siab, xws li hauv kev lag luam aerospace, semiconductor, thiab tshuaj lom neeg.

Cov yam ntxwv

Cov yam ntxwv ntawm lub raj sapphire ua rau nws tsim nyog siv rau hauv qhov chaw kub heev uas lwm cov ntaub ntawv yuav ua tsis tau zoo. Nws tuaj yeem tiv taus qhov kub siab, xeb, thiab hnav, ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov xws li cov raj cua sov, cov raj tiv thaiv thermocouple, thiab cov ntsuas kub siab thiab kub siab.

Ntxiv rau nws cov khoom siv kho tshuab thiab thermal, sapphire lub teeb pom kev zoo hauv qhov pom thiab ze-infrared spectrum ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov uas xav tau kev nkag mus rau qhov muag pom, xws li hauv cov tshuab laser, cov khoom siv tshuaj xyuas qhov muag, thiab cov chaw tshawb fawb siab.

Zuag qhia tag nrho, cov raj sapphire muaj nqis rau lawv qhov kev sib xyaw ua ke ntawm lub zog kho tshuab, kev tiv thaiv thermal, thiab kev pom tseeb ntawm qhov muag, ua rau lawv muaj ntau yam khoom siv hauv ntau yam kev lag luam thiab kev tshawb fawb.

Cov khoom ntawm sapphire raj

Kev tiv taus cua sov thiab siab zoo heev: Peb lub raj sapphire siv rau qhov kub siab txog li 1900 ° C
Kev nyuaj siab thiab ruaj khov heev: Peb lub raj sapphire qhov nyuaj yog txog li Mohs9, nrog rau kev tiv thaiv kev hnav zoo.
Tsis muaj cua nkag: Peb lub raj sapphire yog tsim los ntawm ib qho molding nrog cov thev naus laus zis tshwj xeeb thiab yog 100% airtight, tiv thaiv cov roj seem nkag mus thiab tiv taus cov tshuaj lom neeg xeb.
Thaj chaw siv dav: Peb lub raj sapphire siv tau rau hauv cov ntawv thov teeb pom kev zoo hauv ntau yam cuab yeej analytical thiab tuaj yeem xa pom, infrared lossis ultraviolet lub teeb, thiab nws yog siv los ua qhov hloov pauv zoo rau quartz, alumina thiab silicon carbide hauv cov ntawv thov ua semiconductor
