This study involves ; (i) the synthesis of oxide powders via organic precursor method by using different organic carrier materials, (ii) investigation on the effects of each organic carrier material on the intended and unwanted phase formations, (iii) analyses of formed phases during stages of synthesis, (iv) characterization of the synthesized powders, (v) cyrstallographic studies on the several new crystal phases, (vi) the efforts of holding time during powder calcination, (vii) and further work advices. Different organic carrier materials exhibited different behavior on the synthesis of powders. Synthesis of powders without carrier materials was conducted and the effectiveness of organic carrier materials was confirmed. The factors affecting the purity of the desired phase were stated as the type of the organic carrier material, its cation chelating and/or complexing ability, and the interaction of the functional groups with the constituent cations. The necessity of the organic carrier - cation interaction was highlighted.
