Characteristics
1. The particle size is very small and well-proportioned so that it can be soluted with other elements very well, and lower the physical parametererror of the electronic component.
2. High purity, it is convenient to operate and better for the efficient use.
3. Other elements is very little, little affect for the electronic component, can reduce the error for the practical parameter.
Packing and storage:
25Kg per plastic woven bag, with inner PE bag
Packed in dry and airiness place, no contact with acid and alkali, In good condition, its valid period is one year (the packing should be sealed), if expired, qualified product is still available
