RARE EARTH TANTALATE CERAMIC RESISTING CORROSION OF LOW MELTING POINT OXIDE AND PREPARATION METHOD THEREFOR
The present disclosure discloses a rare earth tantalate ceramic resisting corrosion of a low melting point oxide. A general chemical formula of the ceramic is RETaO4. A method for preparing the ceramic includes: weighing RE2O3 powder and Ta2O5 powder and adding to a solvent to mix, and ball milling the mixed solution with a ball mill to obtain powder A; drying the powder A, and sieving the powder A for a first time to obtain powder B; placing the powder B in a mold for compaction, pre-sintering the powder B to form a block C, cooling the block C to room temperature, grounding the block C with a grinder, and sieving the block C for a second time to obtain powder D; and sintering the powder D to obtain the rare earth tantalate ceramic. The ceramic has high density and strong corrosion resistance to low melting point oxides.
