Spectral Emissivity at High Temperatures
Abstract
Progress on the development work on the Spectral Emissometer used in conjunction with the high temperature multiproperty apparatus is described. The emissometer has been demonstrated to yield state-of-the-art accuracy for the spectral emissivity in the 1.5 to 15 micrometer range above 1300K for opaque solids. Both electrically conducting and opaque insulating samples of high technological interest have been studied. The present work was aimed primarily at increasing sensitivity to allow measurements at lower temperatures and to provide the basis for investigating semi-transparent materials.
