XRD pattern of ball milled Silgrain® milled together with graphite (8:2). I(obs) is the observed measurement. I (calc) is the calculated measurement. I(bkg) is the background, and Obs-Calc is the observed measurement minus the calculated. The inset magnifies the area where we expect to see the graphite peak.
