Thermal Decomposition of Hydrocalumite over a Temperature Range of 400–1500°C and Its Structure Reconstruction in Water

Figure 3

IR spectra of hydrocalumite samples calcined at 500, 1000, and 1500°C (a) and their rehydrated products (b). The IR spectra of an original hydrocalumite sample were presented in the figures for comparison.
