Preparation and Characterization of Ti0.6Cr0.4OxNy Nano-sized Powder

摘要：

　　Ti0.6Cr0.4OxNy bimetallic metal oxynitride nano powder was synthesized by ammonolysis of the nanosized Cr2O3/TiO2 composite powder with n(Ti)∶n(Cr)=6∶4 at 800℃ for 8 h.The precursor and the resulting oxynitride were characterized by Auger electron spectroscope (AES),X-ray diffraction analysis (XRD),electron probe microanalysis (EPMA),transmission electron microscopy (TEM),and BET surface area techniques.The result indicated that the precursor was homogenous mixture of Cr2O3 and TiO2 with high BET surface area.The as-synthesized oxynitride powder contains only Ti0.6Cr0.4OxNy with cubic structure.The BET surface area of the oxynitride powder is 37.42 m2/g and the particle size is in the range of 20~30 nm.
