One that will not reliably detonate from heat/flame, but requires the energy of a donor explosive to detonate.
Many explosive devices consist of a primary and a secondary explosive. The primary consists of a small amount of an explosive that is very easily set off. The primary creates a small explosion that sets off the secondary explosive, which consists of a material that is much harder to set off; usually a primary explosive is the only way. The secondary explosive provides most of the energy of the device, with the primary simply being a trigger. The use of primary and secondary explosives allows for explosive devices that are less likely to go off accidentally.

C-4 is classified as a high explosive due to its rapid rate of decomposition and high energy release. It is commonly used in military applications due to its destructive power.
Primary and secondary explosives. The definitions of these are rather loose, however typically primary explosives will detonate when ignited (example: mercury fulkminate), and secondary explosives require a shockewave to detonate (example: TNT). The most accurate definition is when used in the context of an "explosive train" whereby a fuse ignites the primary high explosive which undergoes deflagration to detonation transition, this detonation produces a shockwave which is used to initiate a secondary high explosive. So explosive compounds are classified into primary or secondary based there primary use.

No, a blasting cap is not a high explosive itself, but rather a small explosive device used to trigger a larger explosive charge. Blasting caps are sensitive explosives designed to initiate a controlled detonation in high explosives like dynamite or other blasting agents.
High Explosive - 1943 is rated/received certificates of: USA:Approved USA:Passed (National Board of Review)
High Explosive, generally meaning that the projectile is packed with TNT or other explosive material.
Yes. It is a high explosive.
Banjo Paterson wrote the poem "High Explosive" in 1917 during World War I.
No, tungsten is not an explosive material. It is a hard and dense metal known for its high melting point and durability.
