Abstract： The corundum ccramics made in different forming Technlogy have various mechanical propertics. Expcriments show that the mechanical propertics of corundum ceramics madeby isostatic pressing are supcrior to those made by casting, and the latter is superior to thosc made by dry pressing.

Key words: corundum, forming, the fracturc toughness
