Abstract
The paper presents the results of studies of the crystal structure, surface morphology and electrical properties of nickel molybdate obtained by hydrothermal method and modified by ultrasound. The influence of the duration of ultrasonic dispersion on the crystallites size, specific surface area, pore size distribution and activation energy of charge carriers of nickel molybdate hydrate is determined. It was found that ultrasound with a frequency of 22 kHz and a duration of 90 min leads to an increase in the total volume of mesopores from 0.135 cm2/g to 0.223 cm2/g with an average diameter of 28.5 nm.
