Abstract

Texture measurements were performed on liquid phase sintered alumina textured by a templated grain growth process. Texture distributions were measured using four techniques (x-ray pole figure, rocking curve, and Rietveld refinement and stereological measurements) and the March-Dollase equation was fit to the measured distributions to yield two parameters (r and f) that describe the texture distribution. The fitting parameters of the x-ray diffraction measurements were compared with data from stereological measurements. The degree of orientation of the textured fraction (the r parameter) determined by the various techniques was in good agreement. The fraction of oriented material (the f parameter) indicated by the Rietveld analysis was higher than the other techniques, while pole figure measurements gave the lowest values. The data from the stereological measurements and the rocking curve method agreed well. The differences and agreements between the results of the various techniques are discussed. Rocking curve analysis was found to be a straightforward method for texturecharacterization of ceramic systems with relatively simple data collection and analysis.
