Abstract
A series of hydroxyapatite powders obtained by chemical deposition using microwave radiation is considered. Calcium nitrate and ortho-phosphoric acid have been selected as sources of calcium and phosphorus. The possibility of using the sorption method for express analysis of the particle size of the formed hydroxyapatite is discussed. It is shown that the sorption analysis of the sizes of nanoparticles in the case of studying hydroxyapatite nanorods makes it possible to approximately estimate the diameter of the forming particles at different stages of synthesis based on the data on the density and specific surface area. The analysis of the specific surface area is carried out using the method of thermal desorption of inert gases. Determination of the aspect ratio of hydroxyapatite nanorods is based on the analysis of scanning electron microscopy data. The difference in the results of calculations of the sizes of nanorods by the sorption method and based on the data on scanning electron microscopy in the maximum case is 70 nm.
