Dynamic High-Pressure Shock Compaction of Diamond Powders
Abstract
The present report summarizes investigations carried out on shock consolidation of diamond powders for fabrication of compacts for electronic substrate applications. Consolidation of various types of commercially available natural and synthetic diamond powders has been performed in this study. The type of diamond and morphology of the powder particles affects the consolidation mechanisms as well as the diamond compact characteristics. It is shown that with the use of appropriate particle size distribution, and therefore a high initial packing density, compacts with optimum physical characteristics crack-free and better than 90% of theoretical maximum density can be obtained. However, about 3-5% transformed graphite and extensive residual strain in the compacts has been detected, both of which severely limit the thermal conductivity. The work contained in this report provides an extensive series of experimental results and mechanistic studies discussing the consolidation behavior of diamond powders by the shock compression technique.
