Translate this pageThe predominant method for synthesizing UO3 is by thermal decomposition of UVI compounds in the presence of O2 . While most actinide oxides are thermally stable with high melting points, -UO3 decomposes at 650 C. Hyper- and hypostoichiometric, UO2+x and UO2x, respectively, are also known and have been analyzed by X-ray crystallography.

  • CF 4 decomposition by thermal plasma processing | SpringerLink

    May 01, 2003Decomposition of CF4 was investigated by thermal plasma method. Thermal plasma processes applied to environmental problems have the features of high temperature, high activity and rapid decomposition rate, so it can perfectly decompose non-decomposed materials like CF4 to a high degree. Before the experiment, thermodynamic equilibrium calculations were performed from 300 K toCited by: 26

  • Decomposition of tetrafluorocarbon in dielectric barrier

    The decomposition of CF4 in dielectric barrier discharge at atmospheric pressure was examined. The effect of O2 contents, N2 contents, and total flow rate on CF4 conversion was experimentally investigated. The maximum conversion of CF4 was about 87% at 5 kV, 15 kHz for the feed gas stream containing 5 sccm CF4, 7.5 sccm O2, and 187.5 sccm Ar. CO, CO2, and COF2 were the main

    Jul 01, 2004The hydrolytic decomposition of CF 4 has been conducted on gallia promoted alumina (Ga-Al oxide) catalysts at 803–903 K and 0.1 MPa. Steady state activity on 20% Ga-Al oxide was 15 times of that on Ce10%-AlPO 4 catalyst, on which the highest activity has been reported. The catalytic activity was further improved by incorporation of sulfate anion in Ga-Al oxide and by applying sol–gel
