For the cement, the surface hydration is the primary process at the initial stage, the kaolin disorganizes and gets into the solution in the form of the silicate tetrahedron and aluminate tetrahedron at the induce stage; the silicon-aluminum tetrahedron network structure is formed at the accelerate stage; the unti-network structure is formed and the rate of heat evolution falls at the decelerate stage; the reaction finished ultimately at the stable stage.

但其水化机理与传统的硅酸盐水泥不同：初始期主要是表面水化，诱导期是高岭土解体并以硅氧四面和铝氧四面体的形式进入液相；加速期形成硅铝四面体网络结构；减速期网络基本形成，水化放热速率降低；稳定期反应速率很低，网络结构趋于稳定。

During the preparation, when the water was used as solvent, the sodium stearate is dispersed by the acid-base neutralization reaction between sodium silicate and stearic acid in water solution, and is encapsuled by the reverse reaction; while when the alcohol/water mixed solution was used, the dispersion and encapsulation of the stearic acid is accomplished via esterification and hydrolysis in alcohol/water solvent.

具体为：以水为溶剂时，利用十八烷酸与水玻璃间发生的酸碱正反应解决其分散问题，而利用其逆反应完成相变材料的包裹，以乙醇／水为混合溶剂时，则利用其酯化、水解双向反应分别完成十八烷酸的分散、包裹过程。

Since FeO is more stable than Cu2O, the FeS is oxidized in preference to Cu2S and the FeO formed is fluxed with SiO2 to form iron silicate slag.

由于 FeO 比 Cu2O 更稳定，因此 FeS 优先于 Cu2S 氧化，形成的氧化铁与二氧化硅熔融形成硅酸铁渣。
