11. He described it as a " primary explosive " which sets off a chain reaction with other explosive materials. 12. An example of such is the lead-free primary explosive copper ( I ) 5-nitrotetrazolate, an alternative to lead azide. 13. A detonator is a device that contains primary explosive wich explodes to initiate the detonation of the main explosive. 14. The heating process typically takes milliseconds to tens of milliseconds to complete and initiate detonation in the primary explosive . 15. Incandescent particles were found most effective for igniting smokeless powder after the primary explosive gasses had heated the powder grains. 16. Therefore, minimising the amount of primary explosive that users must store or carry greatly reduces the likelihood of serious accidents. 17. Some are used as primary explosives , namely lead picrate or potassium picrate which find their use as primers for cartridge ammunition. 18. A blasting cap contains an easy-to-ignite primary explosive that provides the initial activation energy to start the detonation in the main charge. 19. If the tool used to crimp the cap is used too close to the explosives, the primary explosive compound can detonate during crimping. 20. Silver fulminate is a primary explosive , but has limited use as such due to its extreme sensitivity to impact, heat, pressure and electricity.
