Two−phase influence on microstructure and property of ferrite of different purpose was investigated. It is shown that fine dispersed component doped at the second step (milling) effectively brakes growth of grains, promoting reception of dense, homogeneous, fine−grained ferrite materials. Thus such properties as initial magnetic permeability, mechanical strength essentially raise and magnetic losses decrease. Change of modes of baking allows to receive coarse−grained homogeneous materials. Influence of two−phase synthesis on a microstructure and property nickel−zinc, manganese−zinc, lithium−titanic ferrite spinels is more below considered discussed.
