The influence of glycine, glycerine, ethylene glycol and citric acid fuel and their ratio to NO3- on formation and dispersity of Bi2WO6 nanoparticles prepared by combustion synthesis has been studied. The pure crystalline Bi2WO6 with specific surface area 24,8 m2/g and crystallite size of 28 nm was obtained by using glycerine as fuel at its ratio to NO3- of 0,67. The photocatalytic activity of the prepared Bi2WO6 in degradation of methylene blue depended on its specific surface area of samples and solution pH.

La and Sr have recognized as elements of high level radioactive wastes immobilized by solid solution with CaTiO3. For forming solid solution with CaTiO3, the solution combustion synthesis (SCS) process was applied and the powder characteristics and sinterability were investigated. The proper selection of the type and the composition of fuels are important to get the crystalline of CaTiO3. When glycine or the mixtures of urea+citric acid with stoichiometric composition was used, the solid solutions of Ca(La, Sr)TiO3 were entirely produced. The combustion synthesized powder seemed to have a good sinterability with the linear shrinkage of more than 23% up to 1400oC, while that of the solid state reacted powder was less than 19% at the same conditions.
