Abstract

As shown earlier 980 °C reaction products of kaolinite constitute poorly crystallized spinel phase, weakly crystallized mullite, and amorphous SiO₂. The SiO₂ phase was estimated by alkali-leaching technique as described in Chap. 17. The estimation of the other two weakly crystalline phases was attempted by different researchers using QXRD technique. Both crystallinity and quantity of mullite develop largely near 1250 °C exotherm. β-cristobalite usually developed at 1200 °C. The growth rates of both mullite and cristobalite were subsequently determined by the same QXRD technique.
