The paper presents the results of the calculation of the main parameters of electrochemical deposition of microsphere films from a colloidal solution. Within the research, we determined the factors affecting the rate of their growth. The study shows the results of mathematical simulation of the process, characterizing the change in the potential in the interelectrode space, as well as the results of experimental studies of the formation of microsphere structures. Findings of the research were used to estimate the uniformity of the formed structures according to the reflection coefficient. For this purpose we applied the method of full factorial experiment. The study shows that the uniformity of the structures deteriorates with increasing potential difference and pH of the solution. It was also found that with an increase in the process time, the thickness of the structure increases, while the uniformity and ordering decrease. Findings of the research can be used in the further formation of 3D nanocomposites for various applications, for example, to increase the magnetic recording density
