Mechanisms of nano powder Production by means of sol-gel route

In this work production of nano powders by means of sol-gel route were reviewed. Proposed mechanisms, required materials such as solvents or solutes that used for production of industrial nano powders and the effects of them on the characteristics of products were evaluated. Various processes that used for production of nano metal fluorides such as AlF3 and MgF2, nano composites such as Al2O3-ZrO2 and nano metal oxides such as TiO2 and TiO2 adapted to Mg2+ and Br2+ were also reviewed
