Rare earth tantalate RE3TaO7 spherical powder prepared on basis of molten salt method and preparation method of rare earth tantalate RE3TaO7 spherical powder
The invention belongs to the technical field of ceramic powder preparation, and particularly relates to rare earth tantalate RE3TaO7 spherical powder prepared on the basis of a molten salt method and a preparation method of the rare earth tantalate RE3TaO7 spherical powder. According to the rare earth tantalate RE3TaO7 spherical powder prepared on the basis of the molten salt method and the corresponding preparation method, rare earth oxide RE2O3 and tantalum pentoxide Ta2O5 serve as two raw materials, and the rare earth tantalate RE3TaO7 spherical powder synthesized through the molten salt method is high in purity and low in synthesis temperature. According to the method disclosed by the invention, the morphology and the particle size of the powder can be controlled by controlling the proportion of the molten salt to the raw materials, the components of the molten salt, the calcination temperature and the calcination time, and the rare earth tantalate RE3TaO7 spherical powder with high sphericity rate and good fluidity is obtained. In addition, the prepared rare earth tantalate RE3TaO7 spherical powder has the advantages of being uniform in particle size, excellent in performance, stable in quality, high in controllability, suitable for industrial production and the like.
本发明属于陶瓷粉体制备技术领域，具体涉及一种基于熔盐法制得的稀土钽酸盐RE3TaO7球形粉体及制备方法。本发明方案提供的一种基于熔盐法制得的稀土钽酸盐RE3TaO7球形粉体，稀土氧化物RE2O3和五氧化二钽Ta2O5两种原料，及相应的制备方法，采用熔盐法合成的稀土钽酸盐RE3TaO7球形粉体纯度高、合成温度低。而且本发明的方法可以通过控制熔盐与原料的比例、熔盐成分、煅烧温度和煅烧时间来控制粉体的形貌和粒径，获得球形率高和流动性好的稀土钽酸盐RE3TaO7球形粉体。此外，本发明制备的稀土钽酸盐RE3TaO7球形粉体具有粒径均匀、性能优异、质量稳定、可控性强、适用于工业化生产等特点。
