High-energy ball-milling of elemental powder mixtures resulted in the formation of metastable and/or nanocrystalline phases. Both XRD and DSC results show that the ball-milled powers were completely transformed to FeSe0.5Te0.5 with the grain size of a few nanometers during sintering at low temperatures.

The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time
The powders were ground in a milling vial with balls made of 440C hardened steel by using a Spex 8000M high-energy ball milling machine. The milling process and handling of the starting materials and the milled products were carried out in an argon gas environment inside a glove box to protect the particles from oxidation.
