DSC XRD The crystalline properties of the samples

To eliminate the heat history of material, the sample (about 10 mg) loaded in an aluminum crucible was firstly undergone a thermal cycle (containing a heating process from room temperature to 100 °C and a cooling process from 100 °C to 25 °C). Next, another thermal cycle consisted of a consecutive heating and cooling process (in the temperature interval of 25–80 °C) was carried out for the reactants, and another five thermal cycles with the same process were conducted for SSPCMs. All DSC curves of the samples were recorded from the second thermal cycle.
