Alumina Material lian ber berte mizia leh hman dan

Alumina (chemical formula Al2O3) hi inorganic non-metallic material pawimawh tak a ni a, physical leh chemical property tha tak a nei a ni. Industry, electronics, medicine, leh thil dang dangah te hman a ni nasa hle. A material form lian ber berte chu -alumina leh -alumina te an ni a, alumina crystal form hrang hrangte hian property leh application-ah danglamna nasa tak an nei a ni.

Alumina Material chi hrang hrang

1. -Alumina (Corundum) a ni a, a chhuahna hmun hi a nuam hle.

-Alumina hi alumina crystal form stable ber a ni a, natural corundum (ruby leh sapphire ang chi)-a thil awm ber a ni. Crystal structure dense tak a nei a, hardness sang tak (Mohs hardness 9), melting point 2050℃thlenga sang a nei a, chemical stability chak tak tak leh corrosion resistance tha tak a nei bawk. Heng a nihna avang hian -alumina hi wear-resistant materials, ceramic cutting tools, high-temperature refractory materials, leh precision bearings-ah te hman a ni nasa hle.
