Effect of TiO sub 2 on the interaction of dehydroxylated kaolinite with Al(OH) sub 3 gel in relation to mullitisation

Mullite being a material of prime importance in ceramics has drawn attention for a long time. Precursor powder for mullite was prepared in the active state by the aqueous phase interaction of dehydroxylated kaolinite and deposited aluminium hydroxide gel from Al(NO sub 3 ) sub 3 solution. Magnitude of sintering as well as the sintered properties of the compacted mass was found to be influenced by the doping agent, TiO sub 2 .
