Abstract
The present invention relates to a process for preparing a calcium-phosphorus-apatite, essentially characterized by admixing a single solvent of water or an organic solvent compatible with water or a mixed solvent of water with an organic solvent compatible with water with calcium and phosphorus compounds soluble in said single or mixed solvent to prepare a raw material solution, and atomizing the raw material solution into a flame or a heating zone for effecting a thermal decomposition reaction thereof to form a calcium-phosphorus-apatite; a calcium-phosphorus-apatite obtained by the process and having novel characteristics; and the use of the calcium-phosphorus-apatite as a chromatographic packing material.
