A rare earth tantalate ceramic resisting corrosion of a low melting point oxide. The chemical general formula of the ceramic is RETaO4. A preparation method of the ceramic comprises: taking RE2O3 powder and Ta2O5 powder and adding a solvent for mixing, and performing ball milling on the mixture by using a ball mill to obtain powder A; drying the powder A, and then performing primary sieving to obtain powder B; placing the powder B in a mold for compaction and then pre-sintering same to form a block C, performing grinding by a grinding machine after the block C is cooled to room temperature, and then performing secondary sieving to obtain powder D; and sintering the powder D to obtain the rare earth tantalate ceramic. The rare earth tantalate ceramic obtained by using the technical solution has a high compactness, and a strong capacity of resisting the corrosion of the low melting point oxide.
