Lead Styphnate

 

an orange crystalline compound. It is poorly soluble in water and most organic solvents. Its density is 3.1 g/cm3.

Lead styphnate is an explosive initiator with a heat of explosion of 1,550 kilojoules per kg (370 kilocalories per kg), a flash point of 275°C, and a rate of combustion of 25–30 cm/sec at high density. It is obtained by the reaction of sodium styphnate with lead nitrate and is used for compositions in detonators and percussion caps.
