FIELD: medicine.
SUBSTANCE: what is presented is a method for producing carbonate hydroxyl apatite granules consisting in mixing carbonate hydroxyl apatite powder with aqueous solution of gelatine 5 wt % in ratio of the power 1 g to the solution 7.5 ml until smooth; the produced mixture is dispersed through a capillary of a diameter of 1÷2 mm into vegetable oil cooled down to a temperature of T1=-1÷0°C; the produced granules are decanted from the oil and washed with a mixture of ethanol and acetone in ratio 2:1, dried at a temperature of T2=25÷27°C in the air for t=5÷7 hours to hold a spherical shape. The carbonate hydroxyl apatite granules held their spherical shape within the range of 400-800°C, have a diameter of 1-2 mm, specific surface within the range of 32-0.04 m2/g and mesopore volume within the range of 0-0.098 cm3/g.
EFFECT: maintaining the qualities.
