Homogeneity Control In Heterogeneous Materials (A Review)

An analysis of the methods most suitable for ceramics technology for controlling the homogeneity of component distribution in mixtures and the distribution of the porosity (or heterogeneous components) over the article volume is made. A rather rigorous and simple method for evaluation of mixture (sample) homogeneity is suggested that is based on a hierarchic approach and statistical evaluation of the accuracy of determining the concentration of a key component in mixture samples.
