FIELD: chemistry.
SUBSTANCE: invention relates to making ceramic material for mecidine, which can be used in traumatology and orthopaedics, maxillofacial surgery, as well as a drug carrier. A method is proposed for making ceramic biodegradable material consisting of calcium pyrophosphate and tricalcium phosphate, involving preparation of a mixture consisting of calcium pyrophosphate and hydroxyapatite in mass ratio of these components in the interval 75/25-5/95, moulding and roasting. Pyrophosphate is obtained through thermal treatment of brushite powder CaHPO4*2H2O, synthesised from aqueous solutions of calcium nitrate and ammonium hydrophosphate with concentration of 1M-2M, at 550-650°C for 10-20 minutes. When roasting, the ceramics are held at an intermediate temperature range of 700-800°C in isothermic conditions for 1.5-2.5 hours.
EFFECT: obtaining biodegradable material with a uniform microstructure and controlled rate of resorption.
