Setting process of MMSC. (a) Digital photography and SEM images exhibited interconnected porous scaffolds with different 3D shapes cured by MMSC. (b) XRD results indicated that MgO within MMSs had reacted completely, and a new phase, NH4MgPO4·6H2O, formed after setting for 12 h compared with JCPDS#15–0762. (c) SEM image at a high magnification showed lamellar crystals formed between microspheres after setting for 20 min. (d) Element line scan results indicated that the phase composite of the lamellar crystals was NH4MgPO4·6H2O; 1, 2, and 3 pointed to the phases of MgO/Mg2SiO4, Ca7Mg2P6O24 and NH4MgPO4·6H2O, respectively. (e) Schematic diagram of the MMSC setting process.
