Popis:	Testing the chemical stability of high-performance ceramics at temperatures above 1800 K is a demanding task. With the aim to provide an experimental set-up for kinetic studies on gas releasing reactions at temperatures up to 2300 K, a solar reactor has been interfaced to a mass spectrometer. Tracer experiments revealed that the reactor behaves as a continuous ideally stirred tank. This characteristic provides a straightforward path to extract kinetic data for such reactions from gas-phase analysis. The approach is demonstrated by presenting results of a study on the solar thermal reduction of manganese oxide at 2200 K.
