An example of where grinding has damaged the sample is shown below in the powder diffraction pattern for the mineral cinnabar (the bright red polymorph of HgS). Cinnabar is known to be a soft mineral. The sample was gently ground and the data shown above were collected in reflection geometry. Even on this scale, it can be seen that most of the peaks have tails due to peak broadening. The ...
