Variable-Temperature XRD Explorer
Heat the sample and watch the powder pattern evolve: peaks slide as the lattice expands, then split as a phase transition sets in. The readout shows how peak position and relative intensity evolve in this simplified teaching model.
Lattice change Δa/a: 0.00%
High-T fraction (model): 0%
State: low-temperature phase
Schematic teaching model. Peak positions follow Bragg’s law from an idealized linear thermal-expansion coefficient and a single illustrative phase transition near 560°C; real materials show many peaks, material-specific expansion, and richer transition behavior. Intensities and widths are stylized for clarity, and the displayed phase fraction is the model’s input parameter, not a quantity extracted from the plotted intensities.
