What are the 3 categories of high explosives?

The three categories of high explosives are primary explosives, secondary explosives, and tertiary explosives. Primary explosives are very sensitive and are used to initiate a detonation. Secondary explosives are more stable and are commonly used in commercial and military applications. Tertiary explosives are less sensitive and are often used as propellants.


What are the most widely used low explosives?

The most widely used low explosives are black powder, smokeless powder, and pyrotechnic compositions. These explosives are commonly used in firearms, fireworks, and industrial applications due to their controlled burn rate and relatively low sensitivity to shock or friction.


Do explosives contain sulphuric acid?

Can The compatibility group for explosives is shown by?

The compatibility group for explosives is indicated by a letter ranging from A to S, with each letter representing a different level of hazard. This information is used for safe transportation and handling of explosives.


What are medium explosives?

Medium explosives are materials with a moderate amount of power and sensitivity, falling between low and high explosives. They are often used in mining, construction, and military applications for their ability to generate controlled explosions. Examples of medium explosives include TNT (trinitrotoluene) and RDX (cyclotrimethylenetrinitramine).
