Abstract
Dependence of the properties of calcium phosphate compounds on the method of their isolation from biological raw material was studied. Physicochemical studies of the properties of resulting materials were carried out. The proposed procedure allows one to obtain ultrafine powders of biological hydroxyapatite with controllable particle size and composition maximally approaching the composition of bone tissue. It was established that the calcium phosphate compound deposited from the solution that was obtained by demineralization with the solution containing hydrogen chloride 1 mol/L is most close to the mineral matrix of bone tissue.
