LiZn ferrite material with low coercive force
The invention discloses a LiZn ferrite material with low coercive force, which comprises raw materials of Fe2O3, ZnO, Li2CO3, Bi2O3, Mn3O4, Nb2O5, and polyvinyl alcohol, wherein the mole ratio of Fe2O3 to ZnO to 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 LiZn ferrite material with low coercive force is prepared through the following steps: first ball milling, pre-sintering, second ball milling, pelleting and moulding, and sintering.
