The paper studies the influence of asymmetric AC on the speed of obtaining nanosized powder of nickel oxide. It is established that the maximum rate of formation of powder is observed when the ratio of anodic to cathodic density is equal to 2.5. Production of nanosized powders of nickel oxide and creation of nanocomposites based on it is an important direction of development of modern nanotechnology. Nanodispersed powder of nickel oxide is used as electrode material in catalysis, including the synthesis of nanocarbon materials as active element of gas sensors. High-performance super frequency dielectrics is developed on the basis of complex mixtures of oxides of nickel and cobalt. Nanodisperse powders of nickel oxide are obtained in various ways: precipitation pyrolysis, organometallics, copolymerization, sol-gel technology, hydrothermal synthesis, deposition of urea, carbonates of alkali metals and ammonia. These methods are conventionally divided into three groups: chemical, physical and physical-chemical methods. Most of the described methods of obtaining nanosized powders of metals at the current level of development can neither control the growth of particles to obtain nanosized particles of definite composition and of the same size, nor synthesize powders with desired physical and chemical properties, except with the prior metal powders at a constant current. However, if the method is complicated by the use and maintenance of expensive equipment for rectifying
