The evaluation of various NDE techniques as in-process characterization tools during the fabrication development of structural ceramic components for advanced gas turbine applications is presented. Specific techniques and applications that will be discussed are X-ray microfocus real-time fluoroscopy of slip/cast solid interfaces in parts during slipcasting, NMR imaging of organic binder and moisture concentrations in injection molded and slipcast ceramic parts, and ultrasonic transmission and attenuation techniques used to examine parts during slipcasting and subsequent drying.
