Application of ultrafine copper oxide in ferrite magnetic materials
1. Ni-Cu-Zn FerriteIntroduction
Ni-Cu-Zn-based ferrites are generally used as oxide magnetic materials such as coils and the like for high-frequency field applications. Powder metallurgy is commonly used to produce ferrites.
2. production process:
- Weighing:The oxide raw materials such as ferric oxide, nickel oxide, copper oxide, zinc oxide, etc. are weighed so as to reach a predetermined ratio to minimize errors in composition.
- Mixing material: mixing materialmixed dry or wet and crushed,
- temporary roasting:The powder mixture is temporarily calcined.
- Coarse crushing:The material is temporarily roasted and further pulverized.
The need to dry the powder in the case of wet milling of oxides,The characteristics of ferrite mainly depend on the composition;(961.78 degrees)When the layered coil material is fired at a low temperature, the composition should be controlled at a level of 0.1 mol% ferric oxide, nickel oxide, copper oxide or zinc oxide.Using 99.8 percent copper oxide produced by Liaoning Tuohe Technology Co., Ltd. can reduce the error to a minimum.
3. notes:
In the production process, fully stabilized zirconia (FSZ) balls or partially stabilized zirconia (PSZ) balls with high wear resistance are used as the medium balls of crushed ferrite. In the grinding process, zirconia balls with a diameter of 0.5-3.0mm are used as media balls, and the stirring speed is in the range of 2.0-8.0 m/s,and mixed and crushed, temporarily roasted, coarsely crushed and further pulverized.
Generally, the bulk coil material is temporarily roasted and crushed so that the specific surface area reaches 1.0-6.0 meters2/g.
However, it takes a long time to crush the layered coil material, because it needs to be calcined at a temperature lower than the melting point of silver, so as to increase the specific surface area to 3.0-15.0 meters.2/g to improve the low temperature reactivity of the powder.AdoptThe nano-copper oxide of Liaoning Tuohe Technology Co., Ltd. is easier to reduce the melting point of ferrite magnetic materials and achieve the effect of energy saving.
