Ionic Conductivity versus Particle Size of Ball‐Milled …
To this end, zirconia grinding balls with 3 different diameters were used: either 10 mm (10 balls) or 3 mm or 1 mm (30 g, respectively). Independent of the ball size, a mixture of heptane (4.0 mL) and dibutyl ether (0.8 mL) was added. The mixture was milled at 200 rpm between 30 and 240 min (30 min milling time, 30 min rest).
