Revolutionary improvements in operating efficiency or performance characteristics require increasingly hostile operating environments. For example, handling of molten metals exposes materials to extreme temperatures, reducing conditions, and thermal shock. Other applications of interest include leading edges for hypersonic aerospace vehicles, flow-path components for advanced aerospace propulsion systems, refractories for steel, glass, and specialty metal processing, and many others. Ceramic materials and ceramic matrix composites are candidates for many applications that involve severe temperatures, chemical reactivity, or mechanical stresses. 
In recent years, a number of oxide and non-oxide ceramic materials have been investigated for use in extreme environments.  This symposium will examine the critical aspects in four different areas: 1) Synthesis and Processing; 2) Corrosion, Oxidation, and Testing; 3) Mechanical and Thermal Properties; and 4) Characterization. The materials of interest comprise a wide range of ceramics including conventional oxide ceramics such as alumina and zirconia to more specialized compositions such as boride, carbide, and nitride materials. The materials of interest can be monolithic, single phase ceramics, porous materials, multi-phase particulate ceramics, or composites. Ternary carbide materials (i.e., the MAX phases) are the subject of a separate symposium and are excluded from this one.
