Iimpawu zemveliso ye-corundum emnyama

I-Black corundum, eyaziwa ngokuba yi-alumina corundum ephantsi, ikwi-arc furnace, i-bauxite iyanyibilika kwaye yenziwe ngohlobo lwe-α-Al2O3 kunye ne-iron spinel njengeyona nqanaba leminerali ye-crystal emnyama engwevu, ebonakaliswa ngumxholo ophantsi we-Al2O3, kunye nenani elithile le-Fe2O3 (i-10% okanye kunjalo), ngoko inobunzima obuphakathi, ubunzima obuphezulu, ukuxhathisa ubushushu obuphezulu, iimpawu zeqondo lokushisa elishushu.Ikakhulu isetyenziselwa ukusila simahla, njengokusila ngokurhabaxa phambi kweemveliso ze-electroplating, ikakhulu ezisetyenziselwa intsimbi engatyiwa, iimveliso zetsimbi, iglasi yokukhanya, i-bamboo kunye neemveliso zokhuni zokupolishwa kunye nokuqhunyiswa kwesanti. .
