Material characterization of metaschoepite and uranophane. (a) Stacked diffractograms and peak positions from published data (metaschoepite Powder Diffraction File 43-0364; uranophane RRUFF ID R060962.9). (b) Stacked thermograms using DSC-TGA-MS for gravimetric measurements to calculate water content, (c) calorimetric DSC results showing thermal stability up to 1000 °C, and (d) gas profiles of water at mass-to-charge (m/z) 18 from material decomposition.
