Synthesis of Complex Oxides of Rare Elements of Groups IV and V (A Review)

The prospects of using various methods of synthesis for producing extra-pure complex oxides of alkali and bivalent elements with rare elements of groups IV and V of precisely prescribed chemical and granulometric compositions are analyzed. It is demonstrated that only the sol-gel method with inorganic precursors yields nanosize powders of narrow granulometric classes. Epitaxial coatings based on complex oxides can be synthesized by the sol-gel method using organic precursors or true solutions of reactant components.
