zinc oxide for electronic(indirect method)
1, the particle size is small and even: it is convenient to fuse fully in the use process with other ingredient, which may reduce the electronic component physics parameter greatly the deviation.
2, high purity and convenient operation, which enhance the quality goods rate.
3, other element content are little: it affects slightly to the electronic component.
