Abstract

PURPOSE: To provide the subject process comprising the steps of: adding provisionally a dihydrate salt of dicalcium phosphate obtained by causing phosphate and CaCl2 to react with each other in heated hot water whose pH has been adjusted to a specific value after charging of said dihydrate salt, and dehydrating said salt in a slurry state with stirring, thereby to obtain the subject substance suitable for a fluorescent body raw material.
