At beginning, two consecutive blank (empty alumina crucible) experiments were done to get rid of any water absorbed by alumina crucible and establish a stable baseline at 700 0C at the rate of 10K/min by placing the empty crucible on the sample pen (Figure not shown). Then third blank (empty crucible) experiment was done with the same crucible to establish a stable baseline at 300 0C at the rate of 3K/min (Figure 5A) and clear baseline was obtained for weight loss (Black line). Then (4th curve), the empty crucible was weighed and transferred and filled it with the desired air dry MnO2 powder (14.20 milligram). The filled crucible was placed back into the machine in the original position, and closed the cover and the experiment was studied under
