FIELD: chemistry.
SUBSTANCE: invention can be used in chemical and medical industry. Tricalcium phosphate is obtained by reacting aqueous calcium chloride solution and ammonia solution of triammonium phosphate in excess ammonia for 1.0-1.5 hours at temperature of 14-16°C. The obtained filtrate is filtered and washed with distilled water at temperature of 14-16°C and then dried at temperature of 105-120°C.
EFFECT: disclosed method enables to obtain amorphous tricalcium phosphate which does not contain impurities of crystalline defective calcium hydroxylapatite and dicalcium phosphate dihydrate, which has no irritant effect on human skin.
