Reinforcement Mechanisms in Alumina Toughened Zirconia Nanocomposites with Different Stabilizing Agents

Influence of roughness on initial in vitro response of cells to Al2O3/Ce-TZP nanocomposite

“…Moreover, Ce-TZP does not suffer low temperature degradation. The good combination of mechanical properties of this nanocomposite has already been proven [14] and now it is necessary to confirm its good interaction with cells.…”

“…In addition, the following chemical precursors were also used: i) aluminum chloride (Sigma-Aldrich, Spain), ii) zirconium IV-propoxide (70% solution in 1-propanol) (Sigma-Aldrich, Spain), iii) 2-Propanol (99.9% Panreac, Spain) and iv) absolute ethanol (99.97% Panreac, Spain). A colloidal processing route described in Rivera et al [14] and L. A. Díaz et al [15] was followed in order to obtain the nanocomposite. In this route Ce-TZP was coated by an alumina amorphous layer, using aluminum chloride as precursor and subsequently thermally treated in order to activate the formation of γ-alumina transition phase.…”

“…Moreover, Ce-TZP does not suffer low temperature degradation. The good combination of mechanical properties of this nanocomposite has already been proven 14 and now it is necessary to con rm its good interaction with cells. The ideal material to make implants should not be purely tolerated by the host but should interact with biological systems in a way that induces the appropriate host response for a speci c application [26].…”
