Direct Method Zinc Oxide
It has the following features:
1. Small and uniform particle diameter, helps to fuse with other ingredients in service, which can vastly reduce the deviation of physical parameter of electronic component.
2. High purity and easy operation, facilitates the improvement of standard-piece rate.
3. Small content of other elements, has little influence to the performance of electronic component, can reduce the error between the real value and the theoretical value.
