Current Situation and Development of Nano-ZnO

This paper introduces the research developments on manufacture technological of nano-ZnO world-wide. It also describes the manufacture process and characteristics of major technologies as well as the current situation of production of nano-ZnO both at home and abroad. Through the comparison of production prospects of major manufacture technologies,it presents the technological route of the manufacture of nano-ZnO by homogeneous precipitation method with urea as the precipitator and zinc nitrate as zinky raw material. It studies the relative processes,reaction condition,washing of reactant and calcination of nano-ZnO and discusses the existent problems and future research direction.
