Abstract: Many new applications have aggressive design requirements that surpass the capabilities of current ceramics materials. As ceramic material properties are strongly correlated with processing techniques, new innovations in processing ceramics are needed. The sessions proposed for this symposium cover a range of processing techniques, from feedstock to final component, including novel routes using commercial or custom preceramic polymer chemistries. Preceramic polymer development, in terms of chemistry and synthesis, is needed to scale up ceramic material synthesis. In addition to precursor chemistry, novel processes that address the near-net shaping of ceramics and their final densification is critical to technological maturation of these materials. Finally, coating material properties and integration derive strongly from application processes; therefore, a fundamental understanding of the impact of these processes on coating properties is required. In each of these sessions, both modeling (computational, analytical) and experimental work will be considered.

Proposed sessions:

• Purification and refinement of ceramic feedstock
• Pre-ceramic polymer and organometallic precursor development
• Novel near-net shape processes
• Alternative energy sources for curing, drying, debinding, and sintering
• Environmental coating application techniques
• Novel processing of porous ceramics
