In this study, we take advantage of the grain visualization capabilities of DCT in combination with the wealth of single-crystal Laue diffraction data to confirm crystal size, shape, orientation and identity simultaneously on a much more complex sample. From absorption contrast tomography on the same sample, we identify needle and plate morphologies of rhombohedral KBiS 2 that can be attributed to different stages of nucleation and growth, suggesting a screw-dislocation-driven growth mechanism. Applying these measurement techniques to future in-situ studies in extreme environments (especially in aggressive chemical potentials) will allow short-lived, kinetically-trapped phases to be obtained, which should accelerate the discovery of new metastable materials.
