Comminution and mechanochemical activation in oxide ceramics technology (review)

A classification of comminution equipment and conditions influencing the mechanical processing of raw-materials components for obtaining oxide ceramics is presented. It is recommended on the basis of an analysis of comminution (dispersion) and mechanochemical activation of alumina that impact (pressure) - shear (tube, vibratory, planetary, and so forth) mills be used. Mills with average power density 3 - 10 kW/kg are optimal for achieving high specific surface areas and high mechanochemical activation.
