The decomposition behavior of kaolin samples has been carried out by simultaneous TG–DTA experiments. New layer-structure formation during the calcination process was found, and metakaolin compound was detected between 600 and 900 °C. The thermal stability of kaolin samples was then identified by TG–DTA, and the results are …
