Summary

Molecular designed mullite precursor powders were prepared by the co-polymerization of alkoxides. These precursor powders were calcined and then consolidated by the ultra-high pressure isostatic press. This led to the close packing in the green compacts. Sintering behavior depended upon the calcination temperature of the precursors. The compacts of the low-temperature calcined powders sintered into almost full density below liquid formation temperature, if the powders were consolidated by the ultra-high pressure cold isostatic press at IGPa. As a results, ultra-fine mullite precursor combined with the ultra-high pressure cold isostatic press allowed the low-temperature sintering of stoichiometric mullite ceramics.
