Notes:
A new method of synthesizing mullite nanocomposite from raw natural kaolin is presented inthe paper. Raw kaolin is processed by oxidation-reduction fining method and then baked to produce finekaolin powder. The fine kaolin powder is further synthesized into mullite nanocomposite by open-systemhydrothermal crystallization method under normal pressure. With proper controls of NaOH mole ratio inthe hydrothermal solution, crystallization time, and constant temperature, the average grain size ofsynthesized nanocomposite changed from 80nm to 100nm. The morphology of the nanocomposite couldgradually change from platy to short prismatic, lamellar, and needle-like with increasing nucleation rate
