Thermal Decomposition of Hydrocalumite over a Temperature Range of 400–1500°C and Its Structure Reconstruction in Water
Figure 1
XRD patterns of hydrocalumite samples calcined over a temperature range of 400–1500°C and their rehydrated products. (a) Hydrocalumite samples calcined at temperatures ranging from 400 to 900°C; (b) hydrocalumite samples calcined at temperatures ranging from 1000 to 1500°C; (c) rehydrated samples corresponding to those in Figure 1(a); (d) rehydrated samples corresponding to those in Figure 1(b). C: calcite; CA: tricalcium aluminate hexahydrate; Cc: calcium chloride hydroxide; H: hydrocalumite; Hp: hydrophilite; L: lime; M: mayenite; ○: tricalcium aluminate.
