Detonators
The detonators consist of an aluminum shell filled with the required quantity of PETN as base charge and mixture of Nickel Hydrazine Nitrate (NHN) and aluminium powder (ANHN mixture) as priming charge. ANHN mixture is sensitive to flame while PETN is sensitive to the shock wave generated by ANHN mixture. In delay detonators a pyrotechnic element is placed above the ANHN mixture which provides the required delay.
