Synthesis of nano materials and study of the effect of Shock waves on their nano composites

Abstract

Abstract: Vanadium Carbide-Carbon Shells nano material was synthesized using hydrothermal method with the help of several steps and also, nano alpha-aluminium oxide was synthesized using solid combustion synthesis process. Preparation of aluminium oxide/vanadium carbide-carbon shells composite was done through as aluminium oxide reinforced with 5 wt. % vanadium carbide-carbon shells. Test samples were prepared with the help of die. Samples were sintered and the pre-sintered samples were then sintered in a microwave furnace. From the SEM images of aluminium oxide, a platelet like structure was observed and for vanadium carbide-carbon shell, they were appears to a shell-like structure encapsulating small nanoparticles. The XRD pattern of α-aluminium oxide was shown the sharp peak which indicates that the nano material was crystalline and pattern of vanadium carbide-carbon shells was shown semi crystalline nature. Shockwaves of the magnitude of 8 bar and 700 K was produced and impacted on the surface of the specimen held at the driven end. T
