【molecular formula】: ZnO
【molecular weight】: 81.37
【properties】: offwhite fertilizer zinc oxide granularity is less than 1mm。
1.This standard is suitable for low content products of zinc oxide, and zinc oxide mainly gives products of animal husbandry and agriculture.
2.fertilizer zinc oxide in our company is 20 mesh，granularity is less than 1mm。
3.implemented criteria: Q/QHNP70202-1998

1.super thin activated fertilizer grade zinc oxide in our company is used as the zinc additive of insemination. Its main features are that entering soil after fertilizing, chemical reation is so strong and easy to be decomposed by soil and to be absorbed and used by soil.
2.when super thin activatedfertilizer grade zinc oxide in our company is used as the fertilizer，it is fully beyond the production standard requiements of green food because of low pollution heavy metal elements such as,Pb,Cd,As,Hg,etc.
