TL;DR: The role of Na2O-and Li2Odoping on the thermal decomposition of Co3O4 to CoO and the re-oxidation of cobaltous to cobaltic oxide has been investigated using DTA, with controlled rates of heating and cooling, IR and X-ray diffraction spectrometry techniques.

TL;DR: In this paper, the effect of V 2 O 5 and MoO 3 doping on the thermal decomposition of Co 3 O 4 to CoO and the reoxidation of cobaltous to cobaltic oxide was studied using DTA, X-ray diffraction and infrared spectrometry techniques.

TL;DR: In this paper, the influence of MgO and Al 2 O 3 doping on the thermal decomposition of cobaltic oxide to cobaltous oxide and the reoxidation of CoO to Co 3 O 4 was studied using DTA, with controlled rate of heating and cooling, and infrared and X-ray diffraction techniques.

TL;DR: In this article, the effects of calcination temperature and chemical composition on the specific surface area and chemisorbed oxygen of the binary oxides were investigated, and the results showed that the specific area and the amount of chemisored oxygen were increased with an increase in the temperature.
