Study the combustion behavior of metallic boron as fuel in Solid propellants

One of the main ingredients in composite propellants fuels is metal, that been added to increase the efficiency of high explosives. Recently, it is widely used in the propellant of missiles, rockets, gun and in artillery propellants with particularly long-range performance. The first characteristics of boron-containing propellants are high energy density per unit mass of propellant that result is increases in specific impulse of composition. Also, according to the ballistic characteristics of the combustion products of boron, unlike the aluminum (traditional metallic fuel), show optimum ballistic properties. Addition of boron and replacing it instead of aluminum significantly increases the performance of rockets and missiles propellants. According to the points already mentioned, elemental boron can be considered as a replacement by aluminum element; so in this article, the mechanism of combustion behavior of metallic boron as a fuel will be studied.
