High Rate Manufacturing Process for Silicon Carbide Tiles

摘要

Silicon carbide (SiC) ceramic armor is typically hot pressed to obtain full density and superior performance characteristics for demanding applications such as vehicle protection. Hot pressing is however an expensive and slow batch process. This paper describes an alternative, high rate processing approach of Dynamic Magnetic Compaction, which combines a high- density green compaction method with pressure-less sintering. The resulting close to full density material is produced at high throughput and delivers high quality material in near net shape form with a cost advantage. Dynamic Magnetic Compaction has already been successfully applied to process metals, composites, and nano powder products. The successes in these sectors are being translated to the ceramic industry, specifically to process high temperature ceramics such as SiC and BC.
