Abstract
A method is described by which the particle size distribution in opaque materials can be compared with the stationary distributions which, according to the theory of Ostwald ripening by C. Wagner, develop during prolonged annealing. This is done by experimental determination of the linear intercept distributions in the samples and conversion of the theoretical size distributions of spherical and cubic particles to the corresponding intercept distributions. A statistical test makes possible the quantitative evaluation of the agreement between the experimental and theoretical distributions. The practical application of the detailed directions is demonstrated by a numerical example.
