This work is devoted to the study of mesoporous structure parameters of calcium hydroxyapatite powders on the basis of data obtained by nitrogen thermal desorption method. The isotherms of nitrogen desorption/adsorption on the samples of hydroxyapatite and the changes in their porous structure parameters depending on the temperature of the heat treatment are discussed.
