When there are explosions in movies they use a powder, but what is the name of the powder that is used for the explosions? What is the chemical name?

1Are you asking about explosive powder? Blasting powder used to be the case, now it's much more controlled with proper plastic explosive I would assume.– Paulie_DApr 10, 2021 at 9:35

I would think it would depend on the type and scale and desired "look" of the explosion...– HorusKolApr 11, 2021 at 9:25

Usually, explosions are just created with CGI in post-production. However, in the few cases where real explosions are created, it usually depends on the type of explosion required.
Petrol and Propane are highly flammable liquids that can combust from a spark so it is often used practically to create an explosion purely for effect. [1] [2]
As a case study later used for creating the explosion of the Death Star, a mixture of sulfur, potassium nitrate and charcoal was ignited on a minature which produced sparks and debris which were propelled towards the camera as if travelling outward in the vacuum of space. The resulting blast was later reproduced using special effects for Star Wars: A New Hope (Episode IV). [3]
