THERMAL DIFFUSION IN A SOLID SOLUTION OF HYDROGEN IN BETA ZIRCONIUM
Technical Report
·
OSTI ID:4068671
The thermal diffusion of hydrogen in beta zirconium was investigated at two compositions (ZrH/sub 0.4//sub 4/ and ZrH/sub 0.8/ /sub 6/) and at temperatures from 630 to 860 deg C. A diffusion cell containing a sample of zirconium hydride was subjected to a thermal gradient. The hydrogen pressure was determined at the hot and cold ends of the specimen. From the variation of pressure with temperature, the heat of transport was determined. The results varied little with composition. The heat of transport was found to increase with temperature, however, ranging from 6 to 12 kcal/mole. The thermal conductivity was found to vary with increasing temperature from 0.042 to 0.052 cal/cm/sec/ deg C. (auth)
