Zusammenfassung:PROBLEM TO BE SOLVED: To provide an apatite slurry by substantially completely redispersing secondary particles of apatite, and to provide its production method. SOLUTION: This apatite slurry is produced by dispersing apatite particles in an org. solvent having solubility with water. This slurry shows such a dispersion state that the average particle size of the apatite particles is =3μm particle size are substantially not present. The apatite slurry is obtd. by dispersing apatite particles in an org. solvent having solubility with water, supplying the slurry to a stirring mill to pulverize and disperse to such a dispersion degree that particles having >=3μm particle size are substantially not present.
