A comparative quantitative analysis of the shape characteristics and abrasiveness of the grains of powders of natural impact and synthetic diamond is performed. The characteristics of the grain morphology of diamond powders, which have an effect on their abrasive properties, are studied. The shape and specific perimeter of the grain projection, the coefficient of their flattening, and the external specific surface area of the powder are accepted as such characteristics. Differential shape similarity indices of the grain projections of investigated powders and their uniformity with respect to these characteristics as signs of powder quality are determined. The tendencies and degrees of variation of the analyzed characteristics during the transition from impacted diamond powders to synthetic diamond powders are established. For two types of origin of the powder material, a quantitative analysis of the relationship between the detected trends of changes in the grain morphology characteristics of diamond powders and their abrasiveness is performed.
