Jul 01, 2008· The more recent constrained availability of Gallium during 2007, and the resultant price runup, is an example of this intermittent volatility and does not reflect any long term concern about supply. As with many minor metals, the supply/demand balance of Gallium is difficult to fully track, and more difficult to forecast going forward.
Mechanical Grinding. Mechanical grinding is considered to be the most common technique because of its high thinning rate. It is a twostep process which involves coarse grinding and fine grinding. Fine grinding is crucial to get rid of the damage and surface irregularity brought about by the coarse grinding .
