Preparation of High Purity Amorphous Boron Powder
Defence Science Journal, 2005 Amorphous boron powder of high purity (92-94 %) with a particle size of l-2 mm is preferred as a fuel for fuel-rich propellants for integrated rocket ramjets and for igniter formulations. This paper describes the studies on process optimisation of two processes, ie, oxidative roasting of boron (roasting boron in air) and roasting boron with zinc in an ...
