Thermo-mechanical properties of mullite/zirconia reinforced alumina ceramic composites

Shrinkage characteristics studies on conventional sintered zirconia toughened alumina using computed tomography imaging technique

“…As predicted by Chen et al [38], a conical shape is formed by diameter changes along the length after sintering of cylindrical shaped parts. The shrinkage at 1600°C of 2 mm is more compared to 1400°C and is very low for 1200°C with 0.3 mm shrinkage which is in accordance with the reported literature [39].…”

Preparation and Phase Transformation of Mullite-Zirconia from Boehmite and Algerian Halloysite

“…Mullite is one of the basal ceramic materials traditionally used for refractories and is attractive because of its high melting point, thermal expansion coefficient and low thermal conductivity [1,2], and excellent electrical insulating capability [3]. However, mullite ceramics exhibit both low strength and fracture toughness at room temperature.…”

Fabrication of transparent mullite ceramic by spark plasma sintering from powders synthesized via sol–gel process combined with pulse current heating

“…Exhibiting optical transparency and other highly desirable properties such as a low thermal expansion coefficient, high strength, and a good thermal shock resistance, mullite can be applied as an ideal optical window material at elevated temperatures [1][2][3][4]. Among the requirements needed for obtaining transparent mullite ceramics are a high density, a fine grain size with uniform size distribution, the absence of pores at grain boundaries or pores with sizes much smaller than the wavelength of light, the absence of a second phase at the grain boundaries, an isotropic lattice structure and a high surface finish [5].…”
