The first method is simple mechanical wet-milling using a planetary ball mill and spherical grinding media. Spheres of yttria-stabilized zirconia (YSZ) were used as grinding media because of its excellent hardness and chemical inertness properties [25].YSZ is a very dense ceramic material that transfers high impact and shear energy into the biochar as it is milled.
