The paper presents the results of an experimental study of heat and mass transfer during the sublimation of single spherical particles of metal-organic compounds in an inert gas flow. A technique for manufacturing samples of a binary mixture of Y(dpm) 3 and Zr(dpm) 4 is shown. As a result of the research, it was found that heat transfer does not depend on the method of sample preparation, but the front of sublimation becomes three-dimensional much faster for the samples prepared without solvent. It should be noted that after reaching thermal equilibrium, the size of the sample stabilizes and subsequently changes only slightly.
