Black powder rocket propellant is very similar in makeup to old-fashioned gunpowder. The main difference is the presence of a binder, usually dextrin. The commonly used Estes model rocket engines are made with black powder propellant. [2] Black powder propellant must be pressed very tightly in order to function well.
At this time, amateur rockets nearly always employed either black powder, zinc-sulfur (also called "micrograin"), or rocket candy (often referred to as "caramel candy") propellant mixtures. [5] However, such amateur rockets can be dangerous because noncommercial rocket motors may fail more often than commercial rocket motors if not correctly ...

In comparison with black powder, BPN burns significantly hotter and leaves more of solid residues, therefore black powder is favored for multiple-use systems. BPN's high temperature makes it suitable for uses where rapid and reproducible initiation is critical, e.g. for airbags, rocket engines, and decoy flares. It is however relatively expensive.
Graphite – also used as opacifier in rocket fuels to prevent heat transfer by radiation into lower layers of fuels and avoid the related explosions; Carbon black – produces long lasting fine gold sparks in fireworks, also used as opacifier in rocket fuels; Asphaltum – carbon-based fuel, also used as a binder.

The Armstrong Siddeley, later Bristol Siddeley Gamma was a family of rocket engines used in British rocketry, including the Black Knight and Black Arrow launch vehicles. They burned kerosene fuel and hydrogen peroxide. Their construction was based on a common combustion chamber design, used either singly or in clusters of up to eight.
