Bulk samples such as metal blocks, ceramic sintered bodies, or pharmaceutical tablets are aggregates of
microcrystals that can be measured by powder X-ray diffraction. In conventional powder diffraction
measurements, samples need to be filled into a sample holder the size of a typical coin and placed in the
center of the diffractometer. Hence, to perform measurements of bulk samples, it has been necessary to cut
or pulverize samples according to the sample holder, or to use an attachment with an electrically driven
adjustment axis in the thickness direction of the sample. With Rigaku’s bulk sample holder, thick bulk samples
can be easily placed in the diffractometer without any need to cut or pulverize, making it possible to identify
crystal phases of bulk surfaces in a non-destructive manner.
