Nano oxalates of Fe, Co, Ni: Burning rate modifiers for composite solid propellants
Supriya Singh,Gurdip Singh Virk,Pratibha Srivastava 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.27 No.-
We highlight here current research focused on the catalytic activity of nano oxalates of Fe, Co and Nisynthesized by colloidal precipitation method. The catalytic activity of these nano oxalates wasexamined for the thermal decomposition of ammonium perchlorate (AP) and composite solidpropellants (CSPs) using thermogravimetry (TG), TG coupled with differential scanning calorimetry (TG–DSC) and ignition delay measurements. All the nano oxalates showed very high activity as burning ratecatalysts for composite solid propellants (CSPs) containing hydroxyl terminated polybutadiene (HTPB)as binder and AP as oxidizer. CoC2O4 2H2O was found to be the best catalyst in terms of loweringdecomposition temperature of both AP and CSPs
