Engineering Technology and Methodologies

The studies were conducted on grinding powders of black silicon carbide with F180-F60 grit produced by Volzhsky Abrasive Plant. The length, width, perimeter, area and reduced diameter of the grain area were determined by light-microscopical method, the equivalent diameter by the laser diffraction method. The distribution laws of geometric parameters are determined. A direct proportional relationship between the mean equivalent diameter and the average geometric parameters of the grain fractions (length, width, perimeter, equivalent diameter) and the power-law dependence with the average area of the grain fractions have been established
