Metallurgical cokes are composed of graphitic carbon (s2p2) and different inorganic compounds with very different capacities to absorb microwave radiation. Moreover, due to the electric conductivity shown by the metallurgical cokes, microwave radiation produces electric arcs or microplasmas, which gives rise to hot spots. Therefore, when these cokes are irradiated with microwaves some parts of ...

In general, there was a limit to meet skin-affinity and spreadability simultaneously, which are opposite attributes each other. In this study, air jet mill process was tried to satisfy two main properties. Skin-affinity was improved by a wet coating of sericite with a mixture of lauroyl lysine (LL) and sodium cocoyl glutamate (SCG).

In cold wet comminution of polymers in stirred media ball mills, the polymer is comminuted by grinding beads in a liquid solvent. Therefore, the energy input takes place via the stirrer. The influence of the solvent in wet comminution is the subject of current research [ 27 ], but has hardly been investigated for polymers.
