Black powder is a mixture, not an element. It consists of potassium nitrate, charcoal and sulfur in the ratio 75:15:10. It is used in fireworks and was once used to propel bullets in guns(still used with some antique guns).
it is indeed a compound, but its more of a mixture actually.
Boron is typically found in an amorphous brown or black powder form. It does not have a distinct color in its natural state.
Black powder absorbs moisture from the atmosphere
Manganese dioxide (MnO2) is a black powder.
The element you are referring to is iodine. In its solid form, iodine appears as a hard, black, shiny material. When heated, it sublimes directly from a solid to a gas, turning into a brownish-purple vapor. As the vapor cools, it forms brownish powder deposits.
Black powder is much weaker than smokeless powder. Smokeless powder, for this reason, once invented(much after black powder), replaced black powder in guns. However, black powder is still used in fireworks because the extreme explosive power of smokeless powder would prove too dangerous in fireworks.
Black powder, or a black powder substitute such as Pyrodex. Smokeless powder (modern gun powder) should not be used in a traditional muzzle loading firearm.
