Kyocera Industrial Ceramics Corp. recently announced that it has delivered high-temperature silicon nitride SN-282 rotors to a nationally recognized gas turbine engine (GTE) research and development laboratory that is developing a three-kilowatt GTE-powered electrical generator. The SN-282 ceramic material reportedly offers exceptional creep resistance at high temperatures, and Kyocera has the capability to mass-produce ceramic components in complex net shapes for cost-sensitive markets.

SN-282’s high-temperature properties allow for a progressive engine design that does not require rotor blades to have embedded cooling-air channels, a structural element that traditionally presents manufacturing complications and dramatically increases production costs. In addition, the higher operating temperature permitted by ceramic creates significant gains in thermal efficiency. As a result, Kyocera expects the ceramic-equipped GTE to provide a competitive alternative to the internal combustion engine.

It is expected that the ceramic-equipped GTE will compete with (or beat) small gasoline engines on fuel economy while providing the superior longevity and reliability of a gas turbine. Demand for portable three-kilowatt generators for use in land and air applications is expected to grow significantly over the next 10 years.
