cov khoom piav qhia
Corundum yog siv nyob rau hauv cov ntaub ntawv refractory los yog abrasives thiab nws hardness yog thib ob tsuas yog pob zeb diamond. Cov muaju yog lub thoob-puab, columnar, phaj-puab, thiab lwm yam. Lub melting point yog 2050 degree. Kev faib tawm corundum: ntuj corundum (natural corundum yog ntau xim xiav thiab daj, pob tshab thiab ci xim yog hu ua gemstone, liab nrog cov lej ntawm chromium hu ua ruby, thiab xiav nrog kab titanium hu ua sapphire); Artificial corundum (fused corundum) thiab sintered corundum).
