Compaction of aluminium, iron and tungsten powders of particle size 300 BSS has been studied by axisymmetrical geometry. Optimum explosive to powder mass ratio (E/M) to attain maximum density of compact has been determined for different tube diameters in each case. It has been observed that E/M ratio for smaller diameter tube is greater than that of bigger diameter tubes. Explosive and shock wave parameters like velocity of detonation and angle of conical shock wave have also been measured with sulphur coated pin oscillographic technique.
