Ceg alumina, lub hnub qub ci ntsa iab hauv thaj chaw metallurgy, tau ua kom dav dav dav dav hauv kev lag luam rau nws cov khoom thiab ntau cov kev siv. Kab lus no yuav luv luv qhia txoj kev npaj npaj ua, thiab cov ntawv thov ntawm cov alumin, tso cai rau koj txaus siab rau qhov ntxim nyiam ntawm cov txheej txheem metallgical no.
Cais Alumina yog ib qho khoom tau los ntawm kev muab laij tawm los ntawm kev muab laij ua los ntawm Alumhofe lossis kev muaj tsheb Alumina thaum muaj kev hloov pauv theem siab. Cov txheej txheem no, feem ntau ua rau kub ntawm 1200 thiab 1700℃kom tshem tawm cov dej ntawm crystallization, thiab impurities los ntawm cov khoom siv raw, ua rau cov khoom ntshiab alumina. Zaub alumina kev nthuav qhia lub siab melting point, Hardness, thiab hnav tsis kam, nrog rau cov tshuaj lom neeg zoo thiab cov tshuaj insulating.
Cais Alumina yog siv dav hauv ntau daim teb. Hauv kev lag luam ceramics, nws pabcuam ua cov khoom siv raw rau high- Performing ceramics, txhim kho lub hardness thiab hnav tsis kam ntawm cov khoom lag luam kab ke. Hauv cov hluav taws xob teb, muab cov alumina tau siv dav hauv kev tsim cov khoom hluav taws xob xws li capacitors thiab resistors vim nws cov khoom insulating zoo. Ib qho ntxiv, nws tuaj yeem siv ua cov cab kuj catalyst, cov khoom siv regractory, thiab kev sib tsoo hauv nruab nrab, muab kev txhawb zog rau ntau yam kev lag luam.
Raws li cov khoom lag luam me me ntawm cov khoom siv me, muab cov txiaj ntsig zoo heev uas muaj cov txheej txheem npaj nruj, cov khoom ntiag tug, thiab ntau cov ntawv thov. Nrog rau kev nce qib nruam ntawm kev siv thev naus laus zis, kab alumina yuav ua rau nws pom kev thov kom zoo dua, hauv kev tseem ceeb tshaj plaws, txhaj rau kev loj hlob tshiab rau hauv kev tsim kev pab tsim khoom.
