The mineralogical analyze of kaolin was done by XRD analyze method and it was observed that it is pure kaolin. The suspensions were prepared by mixing raw materials in stoichiometric proportions to attain 1:1:2 cordierite composition (MgO:Al 2 O 3:2SiO 2). A typical batch consisted of 39 wt.% of talc, 46 wt.% of kaolin and 15 wt.% of alumina.
