1. Black Powder（Century 7th-18th ） Saltpeter or “Nitre” Chinese as early as the 10th Century Roger Bacon published formula in 1242 Berthold Schwartz invented Gun ~ 1300

(1) Black PowderEvolving 140-86 BC,The formula of the gunpowder wasfirst discovered by Taoist alchemist of ancientChina when trying to make pills of immortalitywhich aimed to keep the king live forever. The medicaments was composed of saltpeter,sulpher and carbon originally. When the mixtureof three components got heated or incited, theexplosion and fire would happen, and finallyproducedthearsenictrioxide(As,o3)

When the mixture of three components got heated or incited, the explosion and fire would happen, and finally produced the arsenic trioxide(As2o3 )

Due to the explosion and fire accidents fromthe alchemy procedure, the explosionfunction of the mixture was applied inmilitary strategist in ancient ChinafirstlyThen the primitive gunpowder was obtained,ironically Before 1956 in China, the eruption mixturewith mainly deflagration behavior was calledas powder, while the one with detonationwas calledas explosive

 Before 1956 in China, the eruption mixture with mainly deflagration behavior was called as powder，while the one with detonation was called as explosive.  Due to the explosion and fire accidents from the alchemy procedure, the explosion function of the mixture was applied in military strategist in ancient China firstly. Then the primitive gunpowder was obtained, ironically

(2) History of the Black PowderIn 80o A.D, the formula of the powder was putforward. One may make in accordance one sulfur,twosaltpeterandthreecharcoalsmeans.1S+2KNO,+3C=K,S+N,+3CO

In 800 A.D, the formula of the powder was put forward. One may make in accordance one sulfur, two saltpeter and three charcoals means. 1S+2KNO3+3C=K2S+N2+3CO2 （2）History of the Black Powder
