Abstract:This review deals with the solution-sol-gel processing (SSG) of powders such as BaTiO_3, MgTiO_3, PbTiO_3, Bi_4Ti_3O_12, La_2Ti_2O_7, Pb(Zr_0.52Ti_0.48)O_3, Pb(Mg_1/3Nb_2/3)O_3 and Ba(Mg_1/3Ta_2/3)O_3. Fine powders of good sinterability can be easily obtained at low temperatures although the process can be expensive and time consuming. We propose a nanocomposite route which utilizes nanophases of different components as a cost-effective alternative to sol-gel process for powder preparation.
