Preparation and polishing performance of lanthanum cerium fluoride polishing powder
Properties of physical and chemical for lanthanum cerium fluoride polishing powder were characterized by techniques of X-ray diffraction,scanning electron microscopy.Space structures were calculated by the inor-ganic crystal structure database(ICSD),and wettability and polishing performance was done using contact an-gle measuring equipment and surface defect detector.It was found that the materials are all made up of agglom-erated near-spherical particles.Below 800 ℃,the product is a mixture of cubic CeO2 and trigonal LaF3,while a-bove 800 ℃,it is a mixture of cubic CeO2 and tetragonal LaOF.When the calcination temperature is 850 ℃,the polishing properties of the products is the best.
