This phase is meta-stable in the ball milled samples and is removed when the hydrogen content of the sample is cycled or when a sample is heated to 570K [4,8]. 2. Experimental Bulkmagnesiumhydride(95wt.%MgH2 and5wt.%Mg) has been bought from Th. Goldschmidt AG. The hydride was mechanically milled under argon by using a Spex 8000 ball mill.

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

Similar to the cyclic voltammetric change of TiC, as the number of cycles increased, the closed area in the curve of the ball-milled WC gradually decreased. In the first cycle, an insignificant reduction peak appeared at around 1.0 V in the curve. This reduction peak may represent toluene residues involved in lithium-ion deintercalation during ...
