Abstract

Thermoโ€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 175ยฐC to 300ยฐC while the second form is removed around 375ยฐC. 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.

## Abstract A hotโ€stage unit, operating over the temperature range from ambient to 1000ยฐC has been used to study the combustion of black powder. Direct observation of heating of mixtures was supplemented by 35โ€mm photomicrography. Results are presented for black powder supplied and mixture prepared
