Published: April 2005

MxOy nanometric powders (Nb2O5, In2O3, and ZrO2) have been efficiently synthesized at low temperatures with the use of simple precursors and with no acid or base catalysis or stabilizing agents. The powders have been characterized by Thermogravimetry/Differential Thermal Analysis, X-ray diffraction, and scanning electron microscopy. The oxides obtained have well-defined crystalline structures, exhibit homogeneity, and crystallite sizes ranging from 9 to 16 nm in diameter.
