Planetary ball mill Pulverisette-6 (Fritsch) was used for the mechanochemical treatment of MMT. Si3N4 balls (d = 20 mm, n = 12) with a total weight of 160 g were used as working bodies. The mass ratio of balls and MMT was 1:10. The milling process continued 0.5–4 h. The rotation speed was equal to 300 rpm.
