An extended instrumental analysis experiment "In situ high-temperature X-ray diffraction study of titanium dioxide phase transformation" is recommended for undergraduates. In this experiment, the phase transformation of TiO₂ was carefully investigated using in situ high-temperature X-ray powder diffraction. The structural changes, including the composition, quantification, lattice constant, grain size, and lattice strains, were analyzed during the phase transformation process. Theoretical knowledge of the basic crystal material structure and a variety of X-ray diffraction analysis skills were combined with the experiments. It is useful for students to acquire knowledge on application, scientific research, and innovation.
