Zirconia-based ceramic is widely used due to their extraordinary qualities; it will be a very useful topic to choose zirconia as research focus. The microstructure control may be achieved by suitable powder characteristics (grain size, agglomeration, purity). During my research Master sintering curve and bimodal sintering models were examined with zirconia. Three constant heating rate experiments were conducted with nano sized yttria stabilized zirconia to characterize master sintering curve. Bimodal sintering experiments were conducted by mixing nano and micron size zirconia powder together and measuring sintering characteristics. Combine simulation with experiment to expect the sintering behavior of zirconia. All experiments were done with Dilatometer furnace and CM furnace in vacuum atmosphere. Density was measured with Archimedes method. Fracture surfaces were examined with SEM.
