Alumina (AL2O3), yog cov khoom siv tawv tawv thiab siv thoob plaws hauv ntau qhov kev lag luam.Thaum raug rho tawm haujlwm thiab sintered, nws tsuas yog tuaj yeem siv los ntawm kev sib tsoo pob zeb diamond.Alumina yog hom ceramic feem ntau siv thiab muaj nyob rau hauv purities txog 99.9%.Nws ua ke ntawm hardness, kub ua hauj lwm (txog 1,700 ° C) thiab zoo hluav taws xob rwb thaiv tsev ua rau nws pab tau rau ntau yam kev siv.
Yuav luag cov ntshiab alumina (99.7%) muab kev ua haujlwm kub siab tshaj plaws rau cov raj tiv thaiv.
