Title: High-purity rare earth element phosphate
Inventor: KIMURA YUJI
IPC: C09K11/81
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain a high purity rare earth element phosphate having a high relative fluorescent luminance, by specifying the contents of Fe and Ca as impurities. SOLUTION: A slightly excessive amount of oxalic acid is added to an acidic aqueous solution of a rare earth element having an ordinary purity to give a rare earth element oxalate, which is washed with water and baked to give an oxide. The oxide is dissolved in a slightly excessive amount of an inorganic acid to give an acidic aqueous solution of the rare earth element, which is added to an aqueous solution of phosphate ions having <=2 atom ppm content of Fe and Ca at 60-100 deg.C to give a gelatin-like precipitate. The gelatin-like precipitate is filtered, washed with water and dried to give a rare earth element phosphate of La, Ce and Tb mixture of hexagonal system, having a base composition formula of Lax Cey Tb(1-x-y) PO4 ((x) is 0.4-0.8; x+y=0.7-0.9), having <=5.0 atom ppm of Fe content and <=5.0 atom ppm of Ca content as impurities, respectively.  The rare earth element phosphate of La, Ce and Tb, mixture of hexagonal system is heat-treated at >=600 deg.C to give a fluorescent substance for wavelength type fluorescent lamp.
