The kinetics of the reduction of fused silica in hydrogen is studied from the viewpoint of the water vapor generation. The water vapor content in exhaust hydrogen gas is monitored at temperatures ranging from 700 to 12003C. A model of the 6ow and di4usion of water vapor generated at the inner surfac

The reaction model for the reduction of NiO pellets by hydrogen has been postulated to consist of two simultane.ous reactions, first, a reaction between NiO and hydrogen gas adsorbed on NiO, and second, a reaction at the boundary between the two solid phases NiO and Ni with hydrogen adsorbed on nick
## Abstract Powdered cerium dioxide (ceria, CeO~2~) as compressed, sintered pellets, of porosity 16.4% and density 5.99 g cm^โ3^, were treated in hydrogen flow at 1 atm and various temperatures to effect reduction. The electrical conductivity was measured in situ during the reduction process. The c
