| 摘 要： | 本文研究了ＣａＯ－ＳｉＯ２－ＭｇＯ－Ｈ２Ｏ体系的热力学，结果表明：ＳｉＯ２ 优先与ＣａＯ水热形成水化硅酸钙，多余的ＳｉＯ２ 才会与ＭｇＯ直接水热形成水化硅酸镁。当没有ＳｉＯ２ 时，ＭｇＯ才会水化形成Ｍｇ（ＯＨ）２。

| Abstract: | Thermodynamics properties of CaO SiO 2 MgO H 2O system under hydrothermal condition were investigated. Results indicate, SiO 2 tend to react with CaO first under hydrothermal condition, calcium silicate hydrates are their products. Surplus SiO 2 may react with MgO, form magnesium silicate hydrates. When there is no SiO 2 exist, MgO will react with water under hydrothermal condition, Mg(OH) 2 forms. |
