Crystallization Studies of Preheated Metakaolinite

  • Akshoy Kumar Chakraborty


It is well-known that metakaolinite forms mullite and β-cristobalite at high temperatures. The alumina component of metakaolinite never crystallizes into corundum during heating. But corundum forms in a kaolinite if it contains alumina minerals as associated phase. Bratton and Brindley (1962) reported that corundum forms easily on heating different kaolinites containing free alumina in the form of diaspore and boehmite.
