There is a need for materials that can be used in devices at elevated temperatures in a variety of applications such as electrical power production, transportation, propulsion, and manufacturing of materials and chemicals. For example, the temperature ceiling of current materials used in the primary heater exchanger of Concentrated Solar Power (CSP) systems have inhibited the enhancement of the thermal-to-electrical efficiency for lower-cost CSP-derived electricity.

Researchers at Purdue University have developed a class of ceramic/metal composite materials for use at elevated temperatures. At such temperatures, these materials are stiff and creep resistant, tough (resistant to crack propagation), thermally cyclable, thermally conductive, electrically conductive, and resistant to oxidation in gases and corrosion in liquids. This material would allow for high-performance, cost-effective primary heat exchangers capable of heat transfer at temperatures greater than 750 degrees Celsius and elevated pressures.
