Kusiyana pakati pa corundum yofiirira ndi yoyera

1. Zipangizo zosiyanasiyana: zinthu zopangira za corundum yofiirira ndi bauxite, kuwonjezera pa anthracite ndi chitsulo. Zinthu zopangira za corundum yoyera ndi ufa wa aluminiyamu oxide.
2. Makhalidwe osiyanasiyana: brown corundum ili ndi makhalidwe monga kuyera kwambiri, kupangika bwino kwa kristalo, kusinthasintha kwamphamvu, kufalikira kochepa kwa mzere, kukana dzimbiri. White corundum ili ndi makhalidwe monga kuyera kwambiri, kudzinola bwino, kukana dzimbiri ndi asidi, kukana kutentha kwambiri komanso kugwira ntchito bwino kwa kutentha. Poyerekeza, kuuma kwa white corundum kuli kokwera kuposa brown corundum.
3. Zosakaniza zosiyanasiyana: ngakhale kuti corundum yofiirira ndi yoyera ili ndi alumina, corundum yoyera ili ndi alumina yambiri,
4. Mitundu yosiyanasiyana: Popeza kuchuluka kwa alumina mu corundum yoyera ndi kokwera kuposa kwa corundum yofiirira, mtundu wa corundum yoyera ndi woyera, ndipo corundum yofiirira ndi yakuda.
5. Kupanga kosiyanasiyana: corundum yoyera imapangidwa ndi ufa wa alumina (zinthu zomwezo monga aluminiyamu ya electrolytic), pomwe corundum yofiirira imapangidwa ndi bauxite yokhala ndi calcium.
6. White corundum ili ndi mphamvu yodula, imagwiritsidwa ntchito kuchotsa zitsulo kapena zosakhala zitsulo, batch front burr, ndi zina zotero. Ili ndi ntchito yopukuta mbali pamwamba, brown corundum imagwiritsidwa ntchito kuchotsa zitsulo zosapanga dzimbiri, carbon steel, aluminiyamu alloy ndi zida zina za hardware surface burr
7. Kugwiritsa ntchito zinthu zosiyanasiyana: corundum yoyera imagwiritsidwa ntchito ndi ogwiritsa ntchito ena apamwamba, chifukwa ndi yolimba bwino podula, kupukuta kwake ndi kwabwino kwambiri, makamaka imagwiritsidwa ntchito pa chitsulo cha kaboni, chitsulo cha aloyi, chitsulo chofewa, mkuwa wolimba ndi zina zotero, ndipo corundum yofiirira imagwiritsidwa ntchito kwambiri pamsika, komanso mlingo wake pamsika ndi waukulu, makamaka pachitsulo choyaka moto, chitsulo chothamanga kwambiri, chitsulo cha kaboni wambiri ndi zina zotero.
Corundum yoyera ili ndi mphamvu yodulira kwambiri, imagwiritsidwa ntchito kuchotsa zitsulo kapena zosakhala zitsulo, batch front burr, ndi zina zotero. Ili ndi ntchito yopukuta zinthu pamwamba, brown corundum imagwiritsidwa ntchito kuchotsa chitsulo chosapanga dzimbiri, carbon steel, aluminiyamu alloy ndi zida zina za hardware surface burr. Brown corundum siipera bwino komanso yowala ngati white corundum.
