Effect of TiO2 on the interaction of dehydroxylated kaolinite with Al(OH)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(NO3)3 solution. Magnitude of sintering as well as the sintered properties of the compacted mass was found to be influenced by the doping agent, TiO2.
