Isometricity Coefficient of Black Silicon Carbide Abrasive Powder Particles

The isometricity coefficients of abrasive powder grain fractions of black silicon carbide of grit sizes F180–F22 are calculated; the powders are produced by roll pressing and jet milling followed by sieving on sieve screens. The distribution law of the isometricity coefficient is established. The degrees and directions of correlations and the reliability coefficients of approximation of linear dependences between the isometricity coefficient and the parameters determining it are determined.
