| abstract | The preparation method of aluminium nitride ceramics disclosed by the invention, it is a kind of using ammonium fluoride as the preparation method of the aluminium nitride ceramics of additive, specifically: ammonium fluoride powder and aluminium nitride powder are weighed respectively by quality proportioning (0.24~0.36): 1, then it is fully ground in corundum mortar uniformly, obtains mixed powder；Mixed powder obtained is fitted into mold, then mold is placed in plasma activated sintering furnace, is densified under 1600~1800 DEG C of sintering temperature, 3~5min of soaking time, 30~40MPa of sintering pressure and nitrogen atmosphere, finally obtains aluminium nitride ceramics.The present invention is using ammonium fluoride as additive, overcome the technical problem that existing oxide addition introduces new impurity in aluminium nitride ceramics sintering process, the generation of the miscellaneous phases such as AlON can be effectively reduced during the sintering process, and do not introduce other impurity, ceramic densifying can also be promoted simultaneously, it is thus possible to obtain the aluminium nitride ceramics with higher degree and high-compactness. |
