FIELD: metallurgy industry, electrolysis. ^ SUBSTANCE: invention refers to inorganic material obtaining technology, and namely to method of obtaining electrolyte containing fine colloid high-purity hydroxylapatite which can be used for applying medical bioactive coatings to implants used in orthopedics and prosthetics. Method includes synthesis of colloid solution of nano-dimensioned hydroxylapatite by adding, at constant mixing, solution of phosphoric acid to saturated solution of calcium hydroxide; preparation of 0.2-5.0 wt % colloid solution of nano-dimensioned hydroxylapatite wherein diluted is calcium hydroxide in amount of 1-5 wt % with mixing till there is complete homogenisation of electrolyte. ^ EFFECT: improving ratio of calcium to phosphorus contained in the coating, eliminating use of corrosive media, and improving electrolyte stabilisation. ^ 1 tbl |
