| Product Name： |
Granular & powdery zinc oxide for electronic（indirect method） |
| Characteristics： |
1, the particle size is small and even: Is advantageous for in the use process with other ingredient full fusions, may reduce the electronic component physics parameter greatly the deviation.
2, the purity is high, is advantageous for the operation, favors enhances the quality goods rate.
3, other element content are few, the content lowly: Affects slightly to the electronic component performance, can reduce the actual value and the error.
4, after makes the powdery zinc oxide the grain to make the pellet zinc oxide to be possible to increase its fluidity, the reduced dust, is advantageous for the mechanization to feed in raw material, the
improvement working conditions, enhance the product delivering.
We may provide each kind of rank for the customer the pellet zinc oxide.
