Physical properties of 8mol% Ceria doped yttria stabilised zirconia powder and ceramic and their behaviour during annealing and sintering

Micro injection molding of micro gear using nano-sized zirconia powder

“…Agglomeration becomes the first critical issue (Trunec and Hrazdera 2005;Bukaemskiy et al 2006;Chen and Mayo 1993). Highly agglomerating powders lead to severe defects.…”

Thermal and crystallization behaviour of 8YSZ–CeO2 system

“…During heating from 873 to 1508 K, the mass of the sample continued to decrease but the mass loss was negligible (0.86%). This can be associated with the elimination of the residual OH groups from the material [25,26]. After annealing at temperatures higher than T S = 1508 K, the mass remained constant.…”

“…The crystallization of 8-CeO 2 -8YSZ and 8YSZ powders was studied in the temperature range between 653 and 1673 K in [26]. By analysing the lattice parameter's dependence on the calcination temperature, the authors concluded that the crystallization of the 8-CeO 2 -8YSZ powder occurs in two steps.…”

“…6, which is shown as a slanting dashed line. To calculate the parameter˛, a single data point for the composition 8-CeO 2 -8YSZ from the previous work [26] was taken into account in the present optimization. The optimized value ofę quals 0.31.…”

Synthesis of nanocrystalline La2O3–Y2O3–ZrO2 solid solutions by hydrothermal method: A crystal growth and structural study

“…Doping is expected to introduce defect and change the lattice energy of crystal. In recent years, considerable efforts have been focused on the fabrication of ceramic materials and rare-earth oxides [8][9][10][11][12][13]. It was found that La 2 O 3 has the greatest effect among the various additives (such as La 2 O 3 , Pr 2 O 3 , Nd 2 O 3 , Er 2 O 3 , etc) [14].…”
