Examples of TG/DTA analysis
The TG-DTA analysis for limestone sample showed an endothermic peak at 912°C with a total weight loss of 43.7% due to the decomposition of CaCO3 to CaO and CO2.
The TG-DTA analysis for Clay 3 is typical of well-ordered kaolin with total weight loss of about 12.8%. There are three distinct peaks as below:-| Peak/°C | Reaction |
| 105.2 | Loss of physical adsorbed water |
| 572.1 | Dehydroxylation of kaolin to metakaolin |
| 975.4 | Transformation of metakaolin to spinel |
