d.V. leybo, d.V. kuznetsov, d.s. Muratov, a.g. yudin (National university of science and technology «MISIS»)
Ni­Mo powders produced by ultrasonic spray pyrolysis and chemical deposition are comparing in this study. specimens were investigated by low-temperature nitrogen adsorption, x-ray diffraction, x-ray fluorescence, scanning and transmission electron microscopy methods. it was shown that the composition of the two-phase material, produced by ultrasonic spray pyrolysis method, is easy to control. powders have spherical shape and high specific surface area.

key words: Nanoparticles, nickel, molybdenum, chemical deposition, ultrasonic spray pyrolysis.
