Chovala cha bulauni chotchedwa corundum, yomwe imadziwikanso kuti adamantine, ndi corundum yopangidwa kuchokera ku bauxite yapamwamba kwambiri ngati chinthu chachikulu, chomwe chimayengedwa mu uvuni wamagetsi wa arc wotentha kwambiri pa kutentha kopitilira 2250℃. Ili ndi zinthu zabwino kwambiri monga kuuma kwakukulu (kuuma kwa 9, kwachiwiri kwa diamod), kukhazikika kwa kutentha kwambiri, kukana kuvala kwambiri, kulimba kwambiri, komanso kudzitseka bwino komanso kutentha kochepa, zomwe zimapangitsa kuti ma abrasives a brown corundum agwiritsidwe ntchito m'magawo angapo amafakitale.
Makamaka,zotsukira za brown corundumingagwiritsidwe ntchito popanga zida zosiyanasiyana zokwawa, monga mawilo opukutira, miyala yamafuta, mitu yokwawa, njerwa zosweka, ndi zina zotero, ndipo ingagwiritsidwe ntchito popera ndi kupukuta zitsulo, zoumba, galasi ndi zipangizo zina zolimba kwambiri. Kuphatikiza apo, ufa wa brown corundum micropowders umagwiritsidwa ntchito ngati zoyeretsera zitsulo komanso zinthu zoteteza kutentha kwambiri, pomwe makhiristo amodzi oyera kwambiri amagwiritsidwa ntchito popanga zinthu zamkati za semiconductors ndicorundum yofiiriraulusi. Mu makina a mankhwala, corundum yofiirira imagwiritsidwa ntchito ngati zotengera zoyatsira, mapaipi ndi zida za mapampu a mankhwala chifukwa cha kukana kwake kuwonongeka komanso mphamvu zake zambiri. Imagwiritsidwanso ntchito kwambiri ngati zinthu zopangira zinthu zopangidwa ndi akatswiri m'mafakitale opanga ma solar photovoltaic, semiconductor, ndi piezoelectric crystal, komanso popanga makoma ndi madenga a furnace otentha kwambiri.
Njira yopangirazotsukira za brown corundumimaphatikizapo masitepe angapo, kuphatikizapo kusankha zinthu zopangira, kuphwanya, kupukuta, kusakaniza ndi kuumba, pyrometallurgy, kuziziritsa ndi kuphwanya, kufufuza ndi kulongedza, chilichonse chomwe chimayenera kulamulidwa mosamala kuti zitsimikizire kuti chinthucho chili bwino komanso chikugwira ntchito bwino.
