Beschreibung
Zusammenfassung:	The present invention provides an apatite slurry in which secondary apatite particles are practically completely redispersed, and provides a method of manufacture therefor. The apatite slurry according to the present invention is characterized in that it comprises apatite particles which are dispersed in a water-compatible organic solvent and has a degree of dispersion such that the average particle size of the apatite particles is 1 mu m or less and particles of 3 mu m or more are practically absent. The method of manufacture for apatite slurry according to the present invention is characterized in that an apatite slurry in which apatite particles are dispersed in a water-compatible organic solvent is fed to an agitation mill and reduced and dispersed until the degree of dispersion is such that particles of 3 mu m or more are practically absent.
