Brown corundum abrasive, yomwe imadziwikanso kuti adamantine, ndi zinthu za corundum zopangidwa kuchokera ku bauxite yapamwamba kwambiri ya abrasive grade monga zopangira zazikulu, zomwe zimayeretsedwa mu ng'anjo yamagetsi yamagetsi yotentha kwambiri kuposa 2250 ℃. Ili ndi zinthu zabwino kwambiri monga kuuma kwakukulu (kuuma kwa 9, kwachiwiri kokha kwa diamondi), kukhazikika kwamafuta ambiri, kukana kuvala kwambiri, kulimba kwambiri, komanso kudzitsekera bwino komanso kutsika kwamafuta, zomwe zimapangitsa kuti ma abrasives a brown corundum akhale ndi ntchito zambiri m'magawo angapo amakampani.
Makamaka,abrasives a brown corundumangagwiritsidwe ntchito kupanga zosiyanasiyana abrasive zida, monga mawilo akupera, mafuta miyala, abrasive mitu, mchenga njerwa, etc., ndipo angagwiritsidwe ntchito pogaya ndi kupukuta zitsulo, ceramics, galasi ndi zina mkulu kuuma zipangizo. Kuphatikiza apo, ma micropowder a brown corundum amagwiritsidwa ntchito ngati metallurgical deoxidisers ndi zida zolimbana ndi kutentha kwambiri, pomwe makristalo apamwamba kwambiri amagwiritsidwa ntchito popanga zinthu zamkati za semiconductors ndibrown corundumulusi. M'machitidwe amankhwala, corundum ya bulauni imagwiritsidwa ntchito ngati ziwiya zochitira, mapaipi ndi zida zapampopi zamankhwala chifukwa cha kukana kwake kovala bwino komanso mphamvu zambiri. Amagwiritsidwanso ntchito kwambiri ngati zida zopangira makina opangira ma solar photovoltaic, semiconductor, ndi piezoelectric crystal industries, komanso pomanga makoma a ng'anjo yotentha kwambiri komanso madenga.
Njira yopangaabrasives a brown corundumzikuphatikizapo masitepe angapo, kuphatikizapo zopangira zopangira, kuphwanya, kugaya, kusakaniza ndi kuumba, pyrometallurgy, kuziziritsa ndi kuphwanya, kuyang'ana ndi kulongedza, zomwe ziyenera kuyendetsedwa mosamalitsa kuti zitsimikizire ubwino ndi ntchito ya mankhwala.
