The creation of new nanostructural materials based on the compounds YBaCuO, BiFeO and FeO has been described. Their structure, morphology and properties have been investigated. The nanopowders of these materials have been produced by burning the nitrate of organic precursors. The possibilities of producing by the energy efficient method from the nanopowders the ceramics of YBaCuO composition with the specified density values in a single step and the ability to obtain the superconducting films of the same composition on a silicon substrate on a SiO-layer have been shown. The methods of producing the BiFeO nanopowder, permitting to obtain the nanostructured ceramics without corresponding secondary phases usually associated with the BiFeO synthesis have been developed. Two methods of the the single synthesis of the FeO nanopowder have been presented. They are: the method of burning the nitrate-organic precursors; the electrochemical three-electrode method, in which as one of the electrodes - anode, serving as consumed material, scrap iron and slurry are used.
