KYOCERA Delivers High-Temperature Ceramic Micro-Turbine Rotors to Nationally Recognized Research Laboratory

Kyocera Industrial Ceramics Corporation today announced that it has delivered high-temperature silicon nitride SN-282 rotors to a nationally recognized gas turbine engine (GTE) research and development laboratory, which is developing a three-kilowatt GTE-powered electrical generator.

Kyocera’s SN-282 ceramic material is the rotor material of choice for the manufacturer’s miniature gas turbine engine due to its exceptional creep resistance at high temperatures and Kyocera's proven 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.

Additionally, 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. 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.

Kyocera has been providing high quality monolithic ceramic components to the gas turbine engine industry for more than 20 years, with facilities in the United States and Japan.
