An assemblage of hydroxyl apatite particles having small and uniform particle size. The median of the particle size is 1 to 10 .mu.m, and at least 90% of the particles in the assemblage have a particle size of not more than 25 .mu.m. The assemblage can be used to pack a liquid chromatography column.
