Abstract

The invention discloses a preparation method of a granular yttrium cerium oxide solid solution. A granular (1-3mum) yttrium cerium rare earth oxide is successfully synthesized from yttrium chloride solution and cerium oxide solid powder (Y2O3 / REO>=99.99%, CeO2 / REO>=99.99%) in the presence of oxalic acid serving as a precipitating agent by adopting a liquid phase precipitation method. According to the preparation method, through controlling influence factors such as feed liquid concentration and precipitation water bath temperature in a synthesis process, the yttrium cerium rare earth oxide which is small in particle size D50 of 1.0-3.0mum and uniform in size distribution is synthesized. The preparation method is short in process, low in cost, convenient to operate, and easy to produce in large scale.

Description

technical field

[0001] The invention relates to the technical field of rare earth applied materials, in particular to a method for preparing a small-particle yttrium-cerium oxide solid solution, in particular to a method for preparing a yttrium-cerium oxide solid solution with particles of 1.0-3.0um in size. Background technique

[0002] At present, with the development of new material technology, rare earth compounds with controllable particle size show a good market prospect, and small particle yttrium cerium oxide rare earth can be used as raw materials in the field of optoelectronics and luminescence. However, rare earth small particle solid solution oxides are used as raw materials to produce luminescent materials, which are more and more favored in technology. Therefore, in the use of its field, the raw materials are required to have a suitable particle size, and the raw materials are required to have a certain particle size distribution. to improve performance.
