Abstract

Multiple-color pyrometric measurement of particles reacting in an electrodynamic thermogravimetric analyzer is discussed. Attempts to measure the emissivity of heated tungsten particles are presented. The data are too scattered to provide reliable results.

Experimental evidence for the sensitivity to noise and the speed of response of pyrometers is presented, and a brief theoretical discussion of the causes is presented.
