Cov yam ntxwv

Cov Lus Qhia Ntxiv

Cov khoom siv tshuaj lom neeg ntawm sapphire ruaj khov heev thiab tsis raug xeb los ntawm cov kua qaub thiab alkalis. Qhov nyuaj ntawm sapphire yog siab heev, nrog Mohs hardness ntawm 9, thib ob tsuas yog pob zeb diamond nyuaj tshaj plaws. Nws muaj kev sib kis zoo ntawm lub teeb, thermal conductivity thiab hluav taws xob rwb thaiv tsev, cov khoom siv kho tshuab thiab tshuab zoo, thiab muaj cov yam ntxwv ntawm kev hnav tsis kam thiab cua tsis kam. Qhov kub ua haujlwm siab tshaj plaws yog 1900 ℃.

Vim tias cov khoom siv sapphire siv lead ua zoo muaj lub teeb xa tau zoo hauv 170nm ~ 6000 nm band, qhov xa tau infrared yuav luag tsis hloov pauv nrog qhov kub thiab txias, yog li cov khoom siv kho qhov muag thiab qhov rais xa tau infrared optical ua los ntawm cov sapphire zoo yog ua los ntawm cov sapphire zoo. Nws tau siv tag nrho hauv cov khoom siv infrared pom kev hmo ntuj tub rog, qhov chaw soj ntsuam kub qis, cov cuab yeej siv siab rau kev navigation, aerospace thiab lwm yam teb.

Cov yam ntxwv thiab daim ntawv thov ntawm sapphire

1, Sapphire nrog nws qhov kev ua tau zoo tshaj plaws, dhau los ua cov khoom siv oxide substrate feem ntau siv (cov ntaub ntawv substrate)

2, Cov khoom siv kho qhov muag, daim iav saib, qhov rai kho qhov muag, qhov rai nrhiav thiab nws daim ntawv thov

3, Sapphire fiber sensor thiab nws daim ntawv thov

4, Doped sapphire ib leeg siv lead ua thermal (lub teeb) luminescence khoom thiab nws daim ntawv thov
