Humidity controlled thermal analysis
The effect of humidity on thermal decomposition of zinc acetylacetonate monohydrate
Abstract
The low temperature formation of crystalline zinc oxide via thermal decomposition of zinc acetylacetonate monohydrate C10H14O4ZnH2O was studied by humidity controlled thermal analysis. The thermal decomposition was investigated by sample-controlled thermogravimetry (SCTG), thermogravimety combined with evolved gas analysis by mass spectrometry (TG-MS) and simultaneous differential scanning calorimetry and X-ray diffractometry (XRD-DSC). Decomposition of C10H14O4ZnH2O in dry gas by linear heating began with dehydration around 60C, followed by sublimation and decomposition above 100C. SCTG was useful because the high-temperature parallel decompositions were inhibited. The decomposition changed with water vapor in the atmosphere. Formation of ZnO was promoted by increasing water vapor and could be synthesized at temperatures below 100C. XRD-DSC equipped with a humidity generator revealed that C10H14O4ZnH2O decomposed directly to the crystalline ZnO by reacting with water vapor.
