theoretical mass loss for pure kaolin of 13.95 wt.%. The TG results show that the main mass loss is between 400–700°C, which actually corresponds to the clay minerals destruction. The mass loss measured in the raw kaolin, of 11.86 wt.%, is not much below the theoretical value. The difference can be attributed to the
