) were introduced into 10 ml zirconia ball-mill jars with two zirconia beads that are 10 mm in diameter. powders were maintained in an inert atmosphere, because the jars were closed inside a nitrogen-ﬁlled glovebox. ball-milling (bm) was performed with a mm-400 shaking ball-mill from retsch, at a frequency of 30 hz for 1 and 5 h.
milling conditions were the following: stainless steel jars (v = 500 cm 3, 100 mm in diameter, 80 mm in height) and balls (32 balls of approximately d = 12 mm, ρ = 7.874 g/cm −3), ball-to-powder weight ratio was 30:1, air atmosphere, basic disc rotation speed was 325 rpm, rotation speed of discs with vials was 400 rpm, milling time was 60 .
