The oxidation of graphite in air in the presence of 0.1 mole per cent of transition metals and inner-transition metal oxides over the temperature range 600" to 700Β°C has been studied. For the first row transition metais, calcium through zinc, the activation energies are at a minimum for calcium, man

The effect of dichlorodifluoromethane, CClsFs and chlorotrifluoromethane, CClFs, on the air oxidation of nuclear graphite was studied by the continuous measurement of weight loss. One-half volume per cent CCl,Fs in air reduced the rate of oxidation of CSF and TSGBF nuclear graphites to about one-thi

The catalytic properties of phthalocyanines of Fe, Co, Ni and Cu for the eleetro-oxidation of hydrazine have been examined. The metal chelates were deposited on ordinary pyrolytic graphite electrodes and their redox properties were studied by cyclic voltammetry. The catalytic activity was found to d
It has been known that the inverse oxidation phenomenon exists under certain conditions. This effect shows that after oxidation, the mass loss on the inside sample can be greater than the mass loss on the outside. The significance of this phenomenon for HTGR safety consideration has been evaluated.
