Crucible for preparing aluminum base intermediate alloy
The invention relates to a crucible for preparing an aluminum base intermediate alloy and in particular relates to a composite material crucible. The crucible for preparing the aluminum base intermediate alloy is made of a material which is prepared from the following raw material components in percentage by mass: 30-50% of Al2O3, 12-20% of Si3N4, 8-12% of SiC, 2-10% of diamond, 8-15% of ZrO2, 3-7% of Y2O3, 3-6% of BN and 3-5% of sintering aid; the sum of the mass percentages of the components is 100%, and the mean grain size of the raw material powder is 100-500nm. The crucible is made of a composite ceramic material which is resistant to high temperatures and corrosion and reactionlessness; and the composite ceramic material is prepared from a plurality of components by sintering, has excellent high temperature resisting property and is not reacted with active metals.
