Sensor use temperature-sensitive magnetic core
The invention discloses a sensor use temperature-sensitive magnetic core which mainly includes, by weight, 68-70% of Fe2O3, 13-17% of ZnO, 0.012-0.018% of Nb2O5, 0.03-0.08% of Bi2O3, 0.02-0.08% of MoO3 and 0.01-0.04% of CaCO3 and the balance of Mn3O4. The sensor use temperature-sensitive magnetic core is prepared by the steps of weighing and mixing, first slurrying, first spray granulation, pre-sintering, grinding, composition correction, secondary spray granulation, molding and sintering with rich oxygen atmosphere, and the like. According to the components and the preparation method, the initial permeability and the sintered density are high, the initial permeability can reach 9000-12000, the Curie temperature can reach 120 DEG C, the sintered density can reach 4.9-5.1g / cm<3>, the sintered magnetic core is high in strength and not fragile. Moreover, the stress of the wire wrapping of the temperature-sensitive magnetic core is small, and the electrical inductance drop is small.
