The Kinetics of The Process of Pepitization During the Hydrolysis of Titanium Nanoparticle

1.Introduction Titania powder can be applied in a wide range of industries like pigments, catalyst support and photocatalysts because of its interesting optical, dielectric and catalytic properties. Many methods of preparing the nanometer titanium have been put forward. Among these, the chemical methods draw the scientific interesting because of their advantages of low cost and low reaction temperature. The Sol-gel method is a very important process to produce the nanometer titania powder. Many researches show that it has great value for the final product by controlling the size, shape and structure of titania precursors. Peptization process has the merit to control the reaction at molecular level [1].
