Effect of Y2O3 on the sintering behavior of sol-gel derived zirconia-mullite precursor through inorganic route

Precursor material for compiling zirconia-mullite composite of higher purity has been synthesized through inorganic route applying co-precipitation and gelation techniques. Pressure-less sintering of the compacted mass has yielded product of dense microsrtucture with generation of tetragonal zirconia dispersed both in the inter- and intragranular position of mullite matrix.
