Corundum cad waxaa lagu sameeyay xaalado heerkul sare oo ka sarreeya 2000 darajo.Iyada oo loo marayo habab badan oo ay ku jiraan burburin, qaabaynta iyo shaandhaynta, waxay ku fiican tahay muuqaalka iyo adkaanta sida walxo gaar ah oo si ballaaran loo isticmaalo.Korundum cad ma aha oo kaliya in ay ku sarreyso adayga, laakiin sidoo kale waa jajaban yahay qaab-dhismeedka, xooggan ee awoodda goynta.Waxa kale oo ay si fiican u qabataa dahaarka, is-afaynta, xidhashada caabbinta iyo kulaylka kuleylka.Dhanka kale, waxay u adkaysataa aashitada iyo alkali daxalka iyo heerkulka sare.Sidaa darteed, sida walxo aad u adag, corundum cad wuxuu leeyahay sifooyin aad u fiican.
