Fa’idodi da rashin amfani na fused farin karfe jade da launin ruwan kasa corundum:

Kayan da aka yi amfani da shi na tushen corundum da aka yi ta hanyar haɗin corundum fused yana da babban abun ciki na alumina. Kwayoyin corundum cikakke ne kuma maras kyau. Babban kwanciyar hankali na sinadarai, babban alumina ko babban alumina clinker ana amfani dashi azaman albarkatun ƙasa don narkewa a cikin baka na Shanghai, cire sauran kayan, da sanyaya frit. Akwai manyan nau’o’in nau’in corundum mai launin ruwan kasa da kuma gaurayawar farin corundum. Lokacin da aka yi amfani da high alumina bauxite don samar da corundum mai launin ruwan kasa, babban alumina bauxite yana buƙatar kafin a kunna wuta kafin electrofusion don cire ruwan da aka lalata da kuma tsarin ruwa a cikinsa don gaggauta aikin lantarki da kuma rage yawan amfani da wutar lantarki. Don cikakken rage tsarin haɗakarwa da kuma kawar da ƙazanta yadda ya kamata, ya zama dole don ƙara yawan adadin anthracite da foda na baƙin ƙarfe zuwa albarkatun ƙasa. Lokacin da alumina ya samar da farin corundum, saboda girman tsabta na kayan aiki, babu buƙatar amfani da hanyoyin ragewa don raba ƙazanta. Abubuwan da ke cikin alumina na Fused Brown Fused alumina ya fi 90%, kuma abun cikin alumina na farin fused alumina ya fi 98%. Ayyukan corundum fused daidai yake da na alumina na sintered, amma wasu fused corundum yana da mafi girman bayyanar porosity.
