Abstract: In this paper we consider the possibility of using the nitrogen thermal desorption method for determining the size of nanoparticles in compositions based on hydroxyapatite and zinc oxide. The compositions in the form of tablets were obtained using a manual water press. The initial powders of hydroxyapatite were obtained by chemical deposition using a microwave radiation. Using the BET sorption method, the specific surface area of the powders is analyzed before and after pressing, and the effect of the composition formulation on the specific surface area is investigated. The calculation of the average sizes of nanoparticles in composites is given on the basis of the results of sorption measurements within the framework of the models of spherical and rod-like nanoparticles. The field of application of the materials under consideration is medicine, including the use of nanocomposites in targeted drug delivery and in bone engineering as bioactive coatings applied to the surface of a metal bioimplant.
