Detailed Description

1. molecular formular : Zn0 2. molecular weight: 81.39 3. appearance: white powder; density 5.606; melting point 1975℃. It is a amphoteric-oxide, insoluble in water or alcohol, soluble in acide and base，zinc oxide is thermothromic changing from white to yellow when heated and in air reverting to white when on cooling. 4. properties: compared with the same product it has following specifications: 1) particle diameter is small and its distribution is uniform. So it is easy to integrat zinc oxide with other ingrediens in using process, which reduces the deviations of eletronic component physical parameters. 2) High purity, easy to operate, be advantageous to increase the quality products rate. 3) It is very litlle content of other elements, which reduce the impaction of the electronic component performances(capabilities) and the errors of the actual value.
