Abstract
A kind of AlON flaky pottery raw powder's production technology, it is characterised in that: by Al powder that granularity is 0.1 ~ 2 m and Al2O3Powder body mix homogeneously, fires at a temperature of 1600 ~ 2000 DEG C after dry-pressing formed in a nitrogen atmosphere for 30 ~ 180 minutes, grinds and makes AlON flaky pottery powder body, wherein Al powder and Al2O3Powder body is with Al:Al2O3Mole ratio uniform that ratio is 1 ~ 5 be mixed.AlON ceramic powder prepared by the present invention is laminated structure, uniform microstructure.
Description
Technical field
The present invention relates to a kind of AlON flaky pottery raw powder's production technology, belong to field of ceramic preparation technology.
Background technology
AlON ceramic material has excellent resistance to elevated temperatures, mechanical behavior under high temperature and thermal property, is widely used in the fields such as Aero-Space, electronics, machinery, metallurgy.But, owing to its oxidation resistance is poor, under conditions of aerobic exists, about about 1000 DEG C start oxidation, therefore, the serious application restricting this material.
Summary of the invention
It is an object of the invention to provide a kind of AlON flaky pottery raw powder's production technology.Its technical scheme is:
A kind of AlON flaky pottery raw powder's production technology, by Al powder that granularity is 0.1 ~ 2 m and Al2O3Powder body mix homogeneously, fires at a temperature of 1600 ~ 2000 DEG C after dry-pressing formed in a nitrogen atmosphere for 30 ~ 180 minutes, grinds and makes AlON flaky pottery powder body, wherein Al powder and Al2O3Powder body is with Al:Al2O3Mole ratio uniform that ratio is 1 ~ 5 be mixed.
Compared with prior art, its advantage is the present invention:
1, the AlON flaky pottery powder body uniform microstructure that prepared by the present invention, angled between sheet and sheet, and be connected with body；
2, each grain surface is that lamellar AlON is connected to form network structure, contacts forming weak interface with other crystal compound tenses.
Accompanying drawing explanation
Fig. 1 is the AlON flaky pottery powder body XRD photo of embodiment 1 preparation；Fig. 2 is the AlON flaky pottery powder body microphotograph of embodiment 2 preparation.
