Properties are determined for electrocorundum grinding grits and powders of different grain size from various producers. Powder particle size distribution and also rheological properties are determined by a static method; bulk and tapping densities, time for emergence from a funnel, natural repose angle, flow criteria, compactability and degree of tapping (indices of powder mobility and compactability), and some dynamic properties using a Revolution instrument. Scanning electron microscopy is used to study features of powder morphology. Results are used for comparative analysis of powders and conclusions are drawn.
