SYNTHESIS OF NANO-ZnO PARTICLES FOR ALUMINUM METALLURGY AS INERT ANODE MATERIAL

A.A.A. Saleh , Y. Fu , X.J. Zhai

金属学报(英文版)

Nano-ZnO particle was produced by evaporating zinc powders in air at air °ow-rate from 0.2 to 0.6m3/h. Nano-ZnO particles was formed by the oxidation of the evapo- rated zinc vapor. X-ray di®raction shows the powders to be ZnO with lattice parame- ters of a=0.3249nm and c=0.5205nm. The particle size...
