Product Description
Purpose
Zinc oxide for soft ferrite is mainly used in the electronic industry to manufacture deflection magnetic cores and other zinc magnesium ferrite magnetic cores, as well as related components of zinc oxide lightning arresters, and magnetic materials for manufacturing electronic structural elements— Ferrites, televisions, radios, electrical communication devices and varistors all use this kind of magnetic materials.
Features
1. The particle size is small and uniform, and it can be dispersed and fused quickly with other materials, which can effectively reduce device parameter deviation.
2. The content of impurities such as copper, manganese, aluminum and iron is small, which has little impact on the performance of electronic components and can reduce the error between the actual value and the theoretical value.
3. High purity, easy to operate, and conducive to improving the rate of authentic products.
