High-performance LiZn ferrite material
The invention discloses a high-performance LiZn ferrite material. The material comprises raw materials of Fe2O3, ZnO, Li2CO3, Bi2O3, Mn3O4, Nb2O5, and polyvinyl alcohol, wherein the mole ratio of Fe2O3, ZnO, and Li2CO3 is (45-50):(10-15):(6-8); the mass fractions of Bi2O3, Mn3O4, and Nb2O5 are 1.5-2.2%, 1.5-2%, and 0.15-0.25%, based on the mass sum of Fe2O3, ZnO, and Li2CO3; and the mass fraction of polyvinyl alcohol is 14-17% based on the mass sum of Fe2O3, ZnO, Li2CO3, Bi2O3, Mn3O4, and Nb2O5. The high-performance LiZn ferrite material is prepared through the following steps: first ball milling, pre-sintering, second ball milling, pelleting and moulding, and sintering.
