Thermo‐analytical techniques such as DSC, TGDTG have been used to study the ternary mixtures of KNO 3 , S and charcoal/carbon black. S exists in two forms, one is called free sulphur on the surface of grains, while the other is termed adsorbed or trapped S. The first form of S, is removed between 175°C to 300°C while the second form is removed around 375°C. The ratio of two forms is altered by the grain and nature of carbon. Carbon black, as compared to charcoal, produces more energy from the oxidation of carbon. The effect of heating rate and the way the sample is placed, is also observed.
