FIELD: manufacturing technology.
SUBSTANCE: invention can be used in making biodegradable materials. Method of producing organo-modified hydroxyapatite by grafting lactic acid involves modifying hydroxyapatite in a solution of ethyl alcohol and lactic acid using ultrasonic dispersion. At least 6-fold centrifugation and dilution in ethyl alcohol is carried out, followed by drying. Weight ratio of hydroxyapatite : lactic acid : ethyl alcohol (95 %) is 1:1–5:5–10.
EFFECT: invention allows to accelerate and simplify production of organomodified hydroxyapatite.
