Kev Piav Qhia Luv:

Pob tshab 80kg sapphire ib leeg siv lead ua muaj cov yam ntxwv zoo thermal, zoo heev hluav taws xob thiab dielectric zog, thiab tshuaj corrosion tsis kam, kub tsis kam, thermal conductivity zoo, siab hardness, infrared nkag mus, tshuaj lom neeg ruaj khov, dav siv hauv cov khoom siv qhov rai infrared kub tsis kam thiab III-V nitride thiab ntau yam khoom siv epitaxial zaj duab xis substrate.


Cov yam ntxwv

Sapphire yog ib yam khoom siv tshwj xeeb uas siv hauv kev lag luam niaj hnub no. Sapphire yog yam khoom nyuaj tshaj plaws, thib ob tsuas yog pob zeb diamond, uas muaj Mohs hardness ntawm 9. Nws tsis yog tsuas yog tiv taus khawb thiab abrasions, tab sis kuj tiv taus lwm yam tshuaj xws li acids thiab alkalis, ua rau nws muaj zog dua li lwm yam khoom siv kho qhov muag. Yog li ntawd, nws zoo tagnrho rau semiconductor thiab kev ua tshuaj. Nrog lub ntsiab lus yaj ntawm kwv yees li 2050 ° C, sapphire tuaj yeem siv rau hauv cov ntawv thov kub siab txog li 1800 ° C, thiab nws qhov kev ruaj khov thermal kuj siab dua li lwm yam khoom siv kho qhov muag. Tsis tas li ntawd, sapphire yog pob tshab los ntawm 180nm txog 5500nm, thiab ntau yam khoom siv pob tshab optical no ua rau sapphire yog cov khoom siv zoo tshaj plaws rau infrared thiab ultraviolet optical systems. Qhov kawg tab sis tsis tsawg tshaj plaws, sapphire kuj yog cov khoom siv nrov hauv kev lag luam hniav nyiaj hniav kub, tshwj xeeb tshaj yog nws qhov purity siab, lub teeb kis tau thiab hardness. Xim ntawm sapphire tuaj yeem hloov pauv raws li qhov xav tau sib txawv, muab rau cov neeg siv khoom nrog ntau yam kev xaiv.
