ABSTRACT:
A process for the production of spherical ceramics particles which are useful as a filling material for osseous defects, as a carrier for drug delivery system and as a packing material for a liquid chromatography includes the steps of forming a first spherical particle consisting of a particulate ceramics-based core and a shell of polymeric material covering the core by using microcapsule technology, and removing the shell from the first spherical ceramic particle to obtain the sperical particles.
