Abstract

An experimental programme is described, in which a number of thermo‐analytical techniques, differential scanning calorimetry (DSC), thermogravimetry (TG and DTG) are applied to investigate the combustion of black powder. The primary aim has been to investigate, and determine qualitatively and quantitatively, the nature of the solid products of combustion. Additionally, standard analytical techniques were applied, to a chemical analysis of the solid products, resulting from the electric arcignition of a sample of black‐powder, under ambient, open air conditions. The solid products formed 33% by weight of the unburned black powder, consisting of K~2~SO~4~ (15%), K~2~CO~3~ (11.5%) and small amounts of KNO~3~ and KNO~2~. The DSC, TG and DTG analyses suggest a mechanism for the combustion, based on phase changes and transition stages of sulfur and KNO~3~, and their interaction with charcoal.

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

## Abstract 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 remov
