Weitere Informationen
This Standard Reference Material (SRM) is intended for use in the analysis of crystallite size through the degree of profile broadening in a powder diffraction experiment. A unit of SRM 1979 consists of two samples of zinc oxide powder, the first with a median crystallite size of approximately 15 nm and a second with a median of approximately 60 nm. These samples are referred to hereafter as the ?15 nm crystallites? and ?60 nm crystallites? respectively. Each sample contains approximately 3 g of powder bottled in an argon atmosphere.
