The reference synthesis of Li 3 PS 4 was performed within the high energy ball mill considering a rotational speed of 800 rpm, 10 mm media size and media filling ratio. Due to the active cooling of the grinding jars, the synthesis was performed as a continuous process without the oftenreported process discontinuities caused by cooling breaks.

As previously stated, the MA process is a method where the elemental metal powders are repeatedly fracturing and rewelding in a high energy ball mill. In the MD process, however, the starting feedstock materials are intermetallic alloys, so that these crystalline alloys tend to convert into an amorphous solid state by relaxing the shortrange ...

The most commonly used method in mechanical milling is the ball milling method, which involves the grinding of a powdered material into extremely fine nanoparticles of 220 nm in size. The ball milling chamber consists of a stainlesssteel container and many small balls of iron, silicon carbides or tungsten carbides.
