Ikoreshwa rya corundum yera

Alumina yera ikozwe mu ifu ya aluminium oxyde kandi itunganijwe hifashishijwe ikoranabuhanga rigezweho kandi ridasanzwe. Umusenyi wumusenyi ufite ibiranga igihe gito cyo gusya, gukora neza, gukora neza, nigiciro gito. Ibice byingenzi ni oxyde ya aluminium (Al2O3) irimo ibice birenga 98%, kandi irimo aside nkeya ya oxyde, okiside silicon, nibindi bice. Zirera ibara kandi zirakonja nyuma yo gushonga mubushyuhe bwo hejuru bwa dogere zirenga 2000 mumashanyarazi. Barajanjaguwe kandi barashushanyije, batandukanijwe na magneti kugirango bakureho ibyuma, kandi byerekanwe mubunini butandukanye. Imiterere yabyo ni yuzuye, ikomeye, kandi ibice bigize inguni zikarishye.
