THE THERMODYNAMIC REQUIREMENT FOR PRODUCING NANOMETER POWDERS BY HYDRO-CHEMICAL METHOD

This paper described the thermodynamic codition of hydro-chemical method for making nanoeter powders,and how to use corrosion figure (E-pH figure) to choose the conditions of gel of gel formation. The experimental results show that this method is a simple, intuited and convenient method. It is not only useful in slope phase system but also in multiple phase co-deposit system.
