摘要：

Mixtures of different MgO/CaO and CaO/SiO2 were treated hydrothermally at 180 to 300 degrees C saturated water vapor pressures for 10h-3days. The results show that tobermorite coexists with Mg(OH)2 and xonotlite phases at 180 degrees C, that xonotlite phase is coexistent with hydrous magnesium silicate when Mg(OH)2 disappears at over 240 degrees C. MgO can enter 14.71wt.% into xonotlite phase, more than in tobermorite phase. At the same time, the variation of lattice parameters in Mg-xonotlite phase is extremely small.
