Thermal Conductivity of Sintered UO, and Al₂O₃ at High Temperatures

Abstract

The thermal conductivities of sintered Al2O3 and UO2 were measured in the ranges 400° to 1700°C and 300° to 2100°C respectively. The conductivity values for Al2O3 agreed with those reported previously at all temperatures investigated. The conductivity of UO, decreased with increasing temperature to a minimum of 0.0050 cal per cm sec °C at about 1400°C, and then increased with increasing temperature to 0.0105 cal per cm sec °C at 2100°C.

Oxidation Behavior of Aerospace Materials in High Enthalpy Flows Using an Oxyacetylene Torch Facility

“…The oxide control materials exhibit the highest front face surface temperatures because they have the lowest thermal conductivity values which are, 6 W·(m·K) −1 and of ~2.4 W·(m·K) −1 for Al 2 O 3 and ZrO 2 , respectively. Both values are lower than the thermal conductivity of graphite and UHTCs .…”
