Product Detail

Khoom cim npe

Sapphire yog cov khoom siv tshwj xeeb uas feem ntau siv hauv kev lag luam niaj hnub no. Sapphire yog cov khoom hnyav tshaj plaws, thib ob tsuas yog pob zeb diamond, uas muaj Mohs hardness ntawm 9. Nws tsis tsuas yog tiv taus khawb thiab khawb, tab sis kuj rau lwm yam tshuaj xws li acids thiab alkalis, ua rau nws muaj zog ntau dua li lwm yam khoom siv kho qhov muag. Yog li ntawd, nws yog qhov zoo tagnrho rau semiconductor thiab tshuaj ua haujlwm. Nrog lub melting point ntawm ib ncig ntawm 2050 ° C, sapphire yuav siv tau nyob rau hauv high-temperature daim ntaub ntawv mus txog 1800 ° C, thiab nws thermal stability kuj yog siab dua li ntawm lwm yam khoom siv kho qhov muag. Tsis tas li ntawd, sapphire yog pob tshab los ntawm 180nm mus rau 5500nm, thiab ntau yam ntawm cov khoom siv kho qhov muag pom tau ua rau sapphire yog cov khoom siv zoo tshaj plaws rau cov tshuab hluav taws xob thiab ultraviolet. Qhov kawg tab sis tsis kawg, sapphire kuj yog cov khoom siv nrov hauv kev lag luam hniav nyiaj hniav kub, tshwj xeeb yog nws cov purity siab, lub teeb kis tau tus mob thiab hardness. Cov xim ntawm sapphire tuaj yeem hloov pauv raws li qhov xav tau sib txawv, muab cov neeg siv khoom nrog ntau yam kev xaiv.
