ABSTRACT:
A method of making a ceramic turbine wheel which includes making a ceramic ring, and providing a ceramic disc within the ring by supporting the external periphery of the ring and hot pressing a ceramic powder within the ring. Ceramic blades are then sintered to the external surface of the ring using a layer of metallic silicon between each blade and the ring. The ring and blades are produced by a reaction-sintering process.
