Dawb alumina yog siab-purity alumina hmoov uas tau yaj hauv lub tshuab hluav taws xob hluav taws xob, thiab cov npauj txias txias tau ua rau cov khoom lag luam ntawm ntau qhov ntau thiab tsawg. Thaum melting alumina hmoov, chromium corundum tuaj yeem tau los ntawm kev ntxiv cov nqi tsim nyog ntawm chromium trioxide.
Sintered corundum abrasive yog alumina lossis alumina hmoov nrog cov ntsiab lus alumina siab, hauv av kom tsawg dua 10 microns, ntxiv cov nqi tsim nyog (xws li zirconia, magnesia) thiab cov binder, extruded thiab txiav ua luv ntuag-zoo li tus (kwv yees li 1 hli nyob rau hauv lub cheeb thiab 5 mm nyob rau hauv ntev), sintered nyob rau hauv ib lub kiln
