Effect of sintering on structure and mechanical properties of alumina–15vol% zirconia nanocomposite compacts

Microstructure and mechanical properties of Al2O3/ZrO2 composites by two‐step sintering

“…In contrast, K IC values were not affected by the reduction in grain size. According to Maneshiana and Banerjee, 57 higher values of %TD present higher K IC in Al 2 O 3 /15 vol% ZrO 2 doped with Y 2 O 3 and MgO. Therefore, results found in this work are in agreement with the results found in literature, mainly concerning H v and K IC behavior.…”

Alumina Toughened Zirconia Nanocomposite Incorporating Al2O3 Whiskers

“…Oxide ceramics are gaining wide acceptance in modern technology considering the combination of properties such as hardness, refractory characteristics, resistance to aggressive media, etc. 1,2 In contrast, the major disadvantage of the ceramic materials is their brittle nature, characterized by the low fracture toughness. 3 Research works have been done focusing on the property improvement that results when alumina (Al 2 O 3 ) and zirconia (ZrO 2 ) ceramics are combined to form ceramic composites.…”

Dielectric properties of PbTiO3/ZnO ceramic nanocomposites obtained by solid-state reaction method

“…However, problems still exist with the thermal expansion mismatch. Several approaches to improve the mechanical strength of the composites by incorporating polymers, metals, fibers or whiskers have been investigated [6][7][8][9][10].…”
