Modern Uses of Explosive Pressure—From Rock Blasting to Synthetic Diamond
Conventional and unconventional commercial uses of high pressures generated by detonation of chemical explosives are described. Recent basic research on factors affecting the performance of explosives in rock blasting are discussed.
The mechanisms and commercial applications of the explosion bonding process for metals are described. In particular, the jetting phenomenon and the processes responsible for bond zone formation are explained.
Experimental results from pioneering research on the effect of explosive shock waves on ceramic powders are presented. Such powders are unusually responsive to sintering and explosive shocking may be a unique way of “cold-working” ceramics.
One of the latest “constructive” commercial uses of explosive pressure, the manufacture of polycrystalline synthetic Diamond, is described. This unique material has established itself firmly as a commercial specialty super abrasive.
