High energy ball milling was conducted with a planetary ball mill, type PM100 (Retsch, Germany). A grinding jar (volume of 50 mL) made of yttrium stabilized zirconia and 200 milling balls (diameter of 5 mm) of the same material were used. Approximately 3 g of starting powder were used, corresponding to a ball to powder weight ratio of 27:1.
