Product Code:
09
Product Name:
Electron grade Zinc Oxide
Molecular formula:
Molecular weight:
Physical properties:
 
Product Description:

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.
