ABSTRACT:
To improve the precision of the cooling fine holes of a large-sized and complex-shaped ceramic gas-turbine nozzle with fine cooling holes, a ceramic gas-turbine nozzle with fine cooling holes has a profile degree of 1.0% or less relative to the blade length, a roundness of the fine cooling holes of 0.3 mm or less, and a straightness of the fine cooling fine holes of 1% or less relative to the blade length. This nozzle is prepared by a method in which two compacts of shroud portions and at least one compact of a blade portion and separately molded are joined by isotropic press molding to be calcined, and the predetermined positions of the resulting calcined compact are subjected to supersonic processing to bore cooling fine holes, the resulting compact is then fired.
