Morphology and Structure Study of Dispersed Nickel-Molybdenum Powders Produced by Different Methods1

摘要

Ni—Mo 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.
