Abstract: | Conclusions At low temperatures water predominates in the compositions of desorbed gases. As the temperature is raised, CO2, CO, O2, CH4, and H2 begin to be liberated, their amount increasing with rising temperature, while the amount of H2O decreases. Prolonged (30-h) vacuum annealing at 523–573°K enables a specimen of the material to be almost completely degassed. A degassed specimen exhibits increased sorptive power, especially with respect to water.Translated from Poroshkovaya Metallurgiya, No. 7(259), pp. 25–29, July, 1984. |
