Extrapolation-analytical method for determination of outer specific surface of powders of superhard materials

A new method is put forward for calculating the outer specific surface of powders of superhard materials. It is based on 3D modeling and involves a mathematical apparatus of affine space mapping. Input data include the grain height as well as the surface area, perimeter, maximum and minimum diameters of the grain projection. The paper provides the results of testing the proposed method on standard synthetic diamond grits and micron powders (as per Ukrainian Standard DSTU 3292-95). The authors offer some recommendations as to practical application of this method.
