    摘要: 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.

    摘要: Microspherical sintered bodies of hydroxyapatite are prepared according to a new specific process wherein a suspension having hydroxyapatite microparticles dispersed in water or an organic solvent or a mixture of water and an organic solvent compatible therewith is atomized into a heating zone maintained above 500.degree. C. whereby spherical agglomerates of hydroxyapatite microparticles formed by drying and solidification of microdroplets of the suspension are sintered while the agglomerates are suspended in the heating zone. Microspherical sintered bodies of hydroxyapatite thus obtained, which may be modified by an optical heat treatment to adjust the surface area of the sintered body and growth of crystals therein, are useful in various fields of industry, for example, as a sorption agent in chromatographic separation.
