Drying was carried out for 2 h (the sample dish was placed on a hotplate with a magnetic stirring in action to prevent gravitational separation of the components). The dried powder was then ground, sieved and calcined at temperature between 800-1200 oC. XRD technique (XRD; Philips PW 1729 diffractometer) was used to identify

Abstract is included in .pdf document. Shock wave consolidation is an innovative processing technique for the densification of initially porous media. A compressive shock wave is introduced in the material by the impact of a high velocity flyer plate. Densification is achieved via intense inhomogeneous plastic deformation, pore collapse, and localized melting around particle surface. The
