ESTIMATION OF SILICON CARBIDE PARTICLE SIZES FROM PHOTOGRAPHS OF CERAMIC SAMPLE SECTIONS

A method for determining the particle sizes of silicon carbide from photo images of ceramic sample sections has been developed. The method is based on estimating the linear sizes of particles by processing and filtering photo sections of ceramic sample sections using a set of image processing algorithms, due to the different contrast of filler particles (silicon carbide) and binder mass. As a test of the proposed approach, a study of photographs of samples of a ceramic hearth plate and a guide for a Seco-warwick kiln was conducted. Descriptive statistics for the maximum linear sizes of silicon carbide particles were determined and an approximate estimate of the granulometric composition was given
