Abstract
The reaction of a powder mixture of ZrSiO4+ Al + Al2O3 has been induced by a techniques combination; milling process, oxidation at 1100°C and spark plasma sintering to produce dense mullite-ZrO2 ceramics. The spark plasma sintering process has showed be a powerful technique of production to sintered and to provoke fast reaction of a mixture in prereaction state of zircon and alumina. Letting to obtain bodies with high tetragonal zirconia contents. The tetragonal zirconia form let the improvement of densification and mechanical properties of mullite-ZrO2 ceramics.
