Khoom Khoom
Sapphire yog ib qho siv lead ua txhuas oxide (Al2O3). Nws yog ib qho ntawm cov khoom siv nyuaj tshaj plaws. Sapphire muaj cov yam ntxwv kis tau zoo tshaj qhov pom, thiab nyob ze IR spectrum. Nws nthuav tawm cov neeg kho tshuab siab zog, tshuaj tiv thaiv, thermal conductivity thiab thermal stability. Nws feem ntau yog siv los ua cov ntaub ntawv qhov rais hauv thaj chaw tshwj xeeb xws li chaw siv tshuab qhov twg khawb lossis kub ua haujlwm yuav tsum tau ua.
