Structure and Composition
AssemblyA benchtop powder X-ray diffractometer with analysis software, a reference database and a silicon standard identifies the crystalline phases in a fired or melted sample. A stereo microscope, a density kit and an optional electron microscope check its microstructure and density. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.

| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | X-Ray Diffractometer 10 parts | 1× | Records the powder diffraction pattern of a ground sample so its crystalline phases can be identified and lattice parameters refined. Core |
| 2 | Zero-Background Sample Holders | 4× | Holds a few milligrams of powder in the diffractometer without adding substrate peaks or an amorphous hump to the pattern. Useful |
| 3 | Phase Identification and Rietveld Software | 1× | Matches a measured pattern against reference patterns to name the phases and refines lattice parameters and phase fractions by the Rietveld method. Core |
| 4 | Reference Pattern Database | 1× | Supplies the reference patterns and crystal structures that a measured diffraction pattern is matched against to name the phases. Core |
| 5 | Silicon Powder Line Position Standard | 1× | Calibrates the diffractometer's 2-theta scale, run alone or mixed into a sample, so the lattice parameters of a new phase can be trusted. Useful, 7.5 g |
| 6 | Stereo Microscope 8 parts | 1× | Magnifies pellets, arc-melted buttons and fracture surfaces for inspection and for placing four-probe contacts on small samples. Useful |
| 7 | Density Determination Kit | 1× | Weighs a pellet in air and immersed in a liquid on the analytical balance, giving its Archimedes density to compare with the X-ray density. Useful, kit |
| 8 | Tabletop Electron Microscope 5 parts | 1× | Images grain size, porosity and second phases at the micrometer scale and measures the elemental composition of each region by EDS. Optional |
