Abstract

 The oxygen content of oxides such as SiO2, ZrO2, Fe2O3, Cr2O3, Co3O4, and of Cr-, Fe- and Co-doped ZrO2 was determined by carrier-gas-heat-extraction. Special attention was given to the accuracy and the precision of the results and to the behaviour of the samples during the process of thermal decomposition. A precision of 0.5 to 1% vol could be achieved.
