Quality index of zinc oxide direct method
GB/T3494-1996
--------------------------------------------------------------------------------
Molecular formula: ZnO
Molecular weight: 81.39
Description: white powder £¬ density 5.606 £¬ melting point 1975 ℃£¬ amphoteric oxide £¬ insoluble in water or ethanol £¬ soluble in acid or alkali solution, yellow at high temperature and recover white after cooling.
Features: In co***rison with likely products, 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.
Application: In rubber industry, ceramic- glaze makeing, frit makeing, Chemical industry and etc.
