Artigo Completo :

A set of standard reference materials (SRM) for powder diffraction were developed at the Laboratory of Applied Crystallography of the Nuclear and Energy Research Institute - IPEN/CNEN, aiming to offer an alternative to the expensive standards produced and sold by the US National Institute of Standards and Technology - NIST. The materials studied as standards were high purity samples of CeO2, Y2O3, Si and Al2O3 submitted to thermal treatments and careful selection by sieving. These standard materials were characterized by diffraction at two synchrotron sources and were compared to the NIST ones. The results show that the produced SRM’s present quality similar or, in some cases, superior to the NIST ones.
