High-frequency low-loss MnZn ferrite, and preparation method thereof
The invention provides a high-frequency low-loss MnZn ferrite. The high-frequency low-loss MnZn ferrite comprises main materials of 30-40mol% of Fe2O3, 36-42mol% of MnO, 10-15mol% of TiO2, the balance of ZnO, as well as auxiliary materials of 0.25-0.35mol% of CaCO3, 0.04-0.6mol% of V2O5 and 0.02-0.03mol% of Nb2O5. Meanwhile, the invention provides a preparation method for the high-frequency and low-loss MnZn ferrite. The preparation method comprises the steps of preparation of a pre-sintering material, preparation of a particle material, and low-temperature sintering. The high-frequency low-loss MnZn ferrite provided by the invention can be used at a high frequency condition safely and steady, and has a very low power; the preparation method for the MnZn ferrite has the advantages of energy conservation and environmental protection.
