Rare earth orthophosphate ceramic powder as well as preparation method and application thereof
The invention provides rare earth orthophosphate ceramic powder as well as a preparation method and application thereof, and belongs to the technical field of ceramic materials. The preparation method of the rare earth orthophosphate ceramic powder provided by the invention comprises the following steps: mixing a rare earth salt solution, a barium salt/strontium salt solution, a phosphorus source solution, a complexing agent and an inorganic solvent, and carrying out complex reaction to obtain sol; the sol is dried, and dried gel is obtained; and calcining the xerogel to obtain the rare earth orthophosphate ceramic powder. The precursor (rare earth salt solution, barium salt/strontium salt solution and phosphorus source solution) in a solution form can be uniformly dispersed on a molecular level, so that the ceramic powder is uniform in size; a sol-gel method is adopted, and the particle size is always kept at the nanoscale in the sol-gel process, so that the ceramic powder with small particle size and uniform distribution is obtained.
本发明提供了一种稀土正磷酸盐陶瓷粉体及其制备方法和应用，属于陶瓷材料技术领域。本发明提供的稀土正磷酸盐陶瓷粉体的制备方法，包括以下步骤：将稀土盐溶液、钡盐/锶盐溶液、磷源溶液、络合剂和无机溶剂混合，进行络合反应，得到溶胶；将所述溶胶进行干燥，得到干凝胶；将所述干凝胶进行煅烧，得到稀土正磷酸盐陶瓷粉体。本发明采用溶液形式的前驱体(稀土盐溶液、钡盐/锶盐溶液、磷源溶液)能够在分子级别上均匀分散，使得陶瓷粉体尺寸均匀；采用溶胶凝胶法，在溶胶凝胶的过程中颗粒尺寸始终保持在纳米尺度，从而获得粒径小且分布均匀的陶瓷粉体。
