Dec 20, 2014 The classical technique for production of iron powder is the reduction of iron oxide 29 Theory of the process: It is the oldest process of production of iron powder by using carbon as the reducing agent In this process pure magnetite (Fe3O4) is usedProduced by burning coke as fuel to heat the iron ore which then gives off carbon monoxide This combines with the iron oxides in the iron ore to produce metallic iron known as pig iron Pig iron is obtained in a molten state that can be moulded as requiredSafe carriage of Iron ores other iron concentrates in bulkGunpowder, also known as the retronym black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosiveIt consists of a mixture of sulfur (S), carbon (C), and potassium nitrate (saltpeter, KNO 3)The sulfur and charcoal act as fuels while the saltpeter is an oxidizer Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and Gunpowder WikipediaThe laser powder bed fusion (LPBF) technology was adapted for use with nonspherical lowcost wateratomized iron powders A simplified numerical and experimental modeling approach was applied to (PDF) The Application of Globular WaterAtomized Iron The wateratomized ATOMET 28, 1001, 4701, and 4801 powders, manufactured by Rio Tinto Metal Powders, were used for additive manufacturing by a laser engineered net shaping (LENS)
