Reaction-forming methods successfully applied to ceramic monoliths and composites having a wide range of compositions are reviewed. Net-shape capabilities and the potential for high purity are the principal advantages of this processing route for both monoliths and composites. Recent results with several different processing techniques demonstrate that superior, often unique, properties can be achieved with these materials if correct microstructural features are achieved. The absence of shrinkage is particularly important for composites because sintering aids are not needed to facilitate particle and reinforcement rearrangements during densification. The absence of sintering aids can allow both monoliths and composites to retain improved properties to higher temperatures. Approaches based on condensed phase:gas-phase reactions and condensed-phase:condensed-phase reactions will be discussed.
