Abstract
ABSTRACTThe possibilities of a new two‐stage method for producing of nickel ferrites are considered. At the first stage, a direct current discharge of atmospheric pressure acts on an aqueous solution of iron and nickel nitrates. A colloidal solution of nickel and iron hydroxides with a particle size of 27–110 nm is formed in the liquid anode of the discharge. At the second stage, the precipitated solid particles are calcined. The result of calcination is the formation of nickel ferrites. The kinetics of the formation of colloidal particles at different discharge parameters were studied. The degrees of transformation of the particles of the initial solutions into colloidal particles, as well as the energy yields, were determined.
