ELECTRON GRADE ZINC OXIDE

ELECTRON GRADE INDIRECT ZINC OXIDE

ELECTRON GRADE ZINC OXIDE
Use:
 
Electron grade Zinc Oxide is widely used in electronic components such as varistor, thermistor, zinc oxide arrester, magnetic material ----- ferrite product etc.

Characteristic and function ：
 
1. Small granule and even granularity. It is advantageous for merging with other material in the course of using, may reduce the deviation of electronic element physics parameter greatly.
2. The purity is high, is advantageous for the operation, favors enhances the good quality rate.
3. The other element content such as copper, manganese, aluminium, iron are micro, affects to the electronic component performance slightly. It can reduce the error between the actual value and the theoretical value.
