Abstract
The thermal diffusivity of gamma-alumina is determined by the photoaco ustic method. The method is calibrated by determining the thermal diff usivity of copper and aluminum. The effect of the chemisorbed hydroxyl groups on thermal diffusivity is studied by degassing the sample at d ifferent temperatures. (C) 1995 American Institute of Physics.
