Abstract To determine and analyze the structure a particular substance, a diffractometer was used. The structure of the substance was unknown, but through the use of the diffractometer in addition to software to analyze the resulting data, the structure can be matched to a specific substance. Two samples were used. The first composition, Scandia and Zirconia, is cubic. The 2nd composition is 65wt% NiO, and 35wt% ZrO2. Introduction A diffractometer is a measuring instrument for analyzing the structure of a usually crystalline substance from the scattering pattern produced when a beam of radiation or particles interacts with it. A picture of a typical diffractometer is shown in Figure 1. Figure 1: Diffractometer Because electrons and neutrons that have wavelengths smaller than a nanometer are relatively easy to use, electrons and neutrons may be used to study crystal structure in a manner very similar to X-ray diffraction. Electrons do not penetrate as deeply into matter as X-rays, hence electron diffraction reveals structure near the surface; neutrons do penetrate easily and have an advantage that they possess an intrinsic magnetic moment that causes them to interact differently with atoms having different alignments of their
