What is a mixture of potassium natrate, powdered charcoal and sulphur called?

A mixture of potassium nitrate, powdered charcoal, and sulphur is known as gunpowder, also commonly referred to as black powder. Historically, this mixture has been the earliest known chemical explosive, consisting of approximately 75% potassium nitrate (saltpeter), 15% charcoal, and 10% sulphur. In this chemical composition, the charcoal and sulphur act as fuels, while the potassium nitrate serves as an oxidizer, providing the necessary oxygen for combustion even in the absence of air. When ignited, these components undergo a rapid chemical reaction, making gunpowder a powerful propellant used in firearms, artillery, and pyrotechnics. Unlike modern smokeless powders, black powder is classified as a low explosive due to its relatively slow decomposition rate and the significant residue it leaves behind.
