Summary

The use of SPS/SHS-type reactions for directly processing ceramics is assessed by considering both results and mechanisms involved in these and other reaction processes. While selected reactions/processing may yield unique compositions or microstructures, these are not generic to such processes. The primary economic advantage is likely to be use of low-cost raw materials for composites. Hot-pressing is likely to be the dominant mode of processing, with nonpropagating reactions being favored. SHS processing to produce powders from which components are subsequently made also offers some opportunities, but again, unique compositions or microstructures are not generic to such processing.
