About rare earth tantalate (RETaO4) preparation technology, guilt is quick et al. with Columbium pentachloride., tantalic chloride and Lanthanum (III) nitrate for initiation material, with benzyl alcohol for solvent, has gone out rare earth niobates LnNbO with solvent structure4(Ln=Ce, Nd, Gd, Yb, Y) and rare earth tantalic acid LnTaO4(Ln=La, Nd, Gd, Dy) nano material, has made corresponding sign to it, although impurity content is less, but synthesis NdNbO4Or NdTaO4There is some monoclinic phases Nb2O5Or Ta2O5.Wang Fuzhi et al. is with rare earth oxide, and tantalum oxide is raw material, adds the once sintered one-tenth rare earth tantalate of cosolvent, but once sintered has certain dephasign, adds cosolvent LiCO3Also certain impurity can be introduced.Chinese patent ZL00126047.2 adds the mixed flux of lithium sulfate-sodium sulfate in the oxide of tantalum oxide, yittrium oxide and strontium carbonate and sinters tantalates into, but this method can introduce some impurity phases.The method that the present invention proposes, overcomes tradition existing methods shortcoming, and not only purity is high, and preparation cost is low, is suitable for batch production, and has better thermal property and mechanical property.
Summary of the invention
It is an object of the invention to provide a kind of novel fire resistant, antioxidation, resistance to wear lanthanide rare tantalates RETaO4(RE=Dy, Eu, Lu, Yb, Nd, Gd, Er) and preparation method thereof, specifically includes following steps: raw materials used for Ta2O5、Dy2O3、Eu2O3、Lu2O3、Yb2O3、Nd2O3、Gd2O3、Er2O3.Weigh raw material in proportion, the raw material prepared mixed in dehydrated alcohol and is placed in planetary ball mill ball milling so that it is can mix homogeneously, mixed powder dried and screened are placed on mould inner pressure real, then carry out pre-burning sintering；Cooling is taken out the sample after presintering and is ground, ball milling, dries, sieves, and the powder after sieving is placed in mould inner pressure real, then carries out double sintering.
During dispensing of the present invention, the mol ratio of rare earth oxide and tantalum oxide is 1:1.
Balls grinding media of the present invention is dehydrated alcohol, and the rotating speed of ball mill is 300r/min～500r/min, and Ball-milling Time is 60～180min.
Baking temperature of the present invention is 60～80 DEG C, and drying time is 10～24 hours.
Dried powder of the present invention crosses 100 mesh sieves or 200 mesh sieves or 300 mesh sieves.
During mixed-powder compacting of the present invention, dwell pressure is 8～12MPa, and the dwell time is 30～60min.
Pre-sintering temperature of the present invention is 800～1100 DEG C, and burn-in time is 5～10 hours.
Double sintering temperature of the present invention is 1500～1800 DEG C, and calcination time is 5～10 hours.
The invention have the benefit that
(1) can mix homogeneously after the mixed powder of ball mill so that it is can composition reaction when calcining.
(2) process purity is high, and impurity content is low, and product preparation cost is low, is suitable for batch production.
