With the rapid growth of global economy, China's rare earth industry has also achieved rapid development, but the application of lanthanum and cerium, as the main elements of light rare earth minerals in north China, has not made breakthrough progress, and the price of lanthanum and cerium products has been hovering at a low level.

"At present, lanthanum and cerium products in the main application fields abroad are still in the glass grinding industry, which can be divided into industrial grinding and civil grinding. "Wang Hongyan introduced.

"Our goal is to develop lanthanum, cerium and rare earth downstream technology applications, expand high-end rare earth applications, and promote the development of Semiconductor, information and other industries in China." Zhang hailong said.

For this reason, Inner Mongolia established the rare earth polishing material development and industrialization project, which determined the basic method of preparing high-performance cerium oxide polishing material with rare earth carbonate as raw material, and added appropriate auxiliary materials in this process to improve the surface characteristics and sphericity of polishing material. A new type of high performance cerium oxide polishing material with excellent polishing performance was prepared by appropriate post-treatment and surface modification.
