FIELD: construction.
SUBSTANCE: invention claims method of obtaining nano-sized powders based on tricalcium phosphate and hydroxylapatite system for ceramicbiomaterial synthesis. Invention concerns calcium phosphate ceramic materials intended for manufacturing of bone grafts and/or defect area replacement for various bone pathologies. Humid powders obtained by chemical reaction are flushed by organic fluids to remove water excess. Ultradisperse calcium phosphate powders with specific surface area of over 90 m2/g are obtained after drying and thermal processing. Nano-sized powder composition is close to natural bone tissue (corresponding to hydroxylapatite and tricalcium phosphate system). High specific surface of powders allows for their application in obtaining biomaterials with fine dispersed or nanocrystalline structure.
EFFECT: reduced aggregation degree, enhanced specific surface.
