In the last twenty years, engineering ceramics evolved with a fairly high rate and many engineers aimed at ambitious substitutions particularly in the thermomechanical field.
Even if so many failures happened, interest for those applications must not decrease since their characteristics are steadily improving and because numerous new concepts have to be designed to reach fruitful and efficient applications.
In this mind, the paper deals with a new turbine concept exploiting the best of ceramics characteristics, forming processes and aiming steadily at a mass production cost reduction.
Conventional radial ceramic turbine are still expensive to manufacture since proof-testing, due to the high refusal rate, reduces production.
With the demonstration of this new concept, more ambitious devices as new automotive gas turbines can be considered, for, ceramics seem to be the only way relevant to a large efficient and economical application.
