Optical thermophysical characteristics of the condensed phase of combustion products and heatproof materials

  • 20 Accesses

Abstract

An unconventional unit for experimentally studying the optical thermophysical properties of materials over a wide temperature range is described. Results are presented of studying the temperature function and dispersion of the absorption index for the condensed phase of the combustion products of a metalbearing fuel and of the emittance of fiber fireproof materials.
