grinding calcined problem

An insight into the surface properties of calcined ...

2014-8-5  Interestingly, the γ s d value significantly diminished by grinding (milling) the calcined samples (16% for MK-750 and 17% for MK-940). With the grinding of the metakaolinitic samples and a consequent decrease of the particle size , an increase of the overall surface energy could be expected. However, after grinding, the potential of the surface to undergo London dispersive interactions and/or Debye
