Abstract
The use of magnesium oxide, reactive alumina and aluminium oxide as a base provides for a new erosion-resistant material upon sintering.
Claims10
A powder comprising (in % by weight):
- from 96.0% to 99.9% of aluminum oxide;
- and
- reactive magnesium oxide in an amount of from 0.1% to 4.0%, to form spinel with the aluminum oxide present, the reactive magnesium functioning as a temporary binder phase;
- wherein aluminum oxide is present as tabular alumina.
