Structural Uniformity of Porcelain Articles

Resumo

The uniformity of the structure of porcelain articles in terms of the orientation of the quartz particles (grains) and the distance between them was evaluated by means of optical microscopy. The distributions of the number of quartz grains along the maximum horizontal and vertical dimensions as well as the distribution of minimum intergrain distances along the vertical and horizontal directions, which are influenced by the different orientation of the particles in the material and the uniformity of the volume distribution of the material particles, were obtained. The deviations of local distributions from the base distributions make it possible to evaluate the structural uniformity of the investigated materials and articles and to analyze the effect of the molding method on their structural features.
