Spectral Emissivity at High Temperatures

Abstract

The status of the Spectral Emissometer used in conjunction with the high temperature Multiproperty Apparatus is described. The measurements of opaque materials, both electrically conducting, in the form of thin-walled tubes, and electrically non-conducting, in the form of small solid cylinders, has become a routine operation in the 0.4 to 15 micro range above 1300 K. The feasibility of, and techniques for, measurement of semi-transparent materials are described.
