When they are cooled below the stable temperature region of the α phase, crystals of belite (Ca2SiO4 solid solutions) inverted to the α′H phase without a change in chemical composition and gave six sets of lamellae within the crystals. After this transition remelting reaction occurred within the inverted α′H‐phase grains, the liquid phase became nucleated and grew heterogeneously on the lamellae boundaries, resulting in a decrease in impurity concentration in the host α′H phase. When the exsolved liquid wetted the lamellae, complete dissolution of the parent crystals occurred during slow cooling. A variety of microtextures resulted, depending on both quenching temperature and cooling rate.
