Cementitious yttria products [PDF]
, 1978 An investigation has been made of the physical properties and formation conditions of cements formed in the yttria/salt/water system. Cementitious binders were of the nominal Y/sub 2/(OH)/sub 5/X.H/sub 2/O type (where X represents the Cl/sup -/ or NO/sub 3//sup -/).

Effect of sintering cycle on the strength and translucency of multilayered zirconia
Journal of Prosthodontics, EarlyView.Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Journal of Prosthodontics, EarlyView.Abstract Purpose This study investigated the influence of cement gap size on the marginal and internal fit, and cement gap size and type on retention of additively manufactured zirconia (AM‐Z) crowns on titanium bases (Ti‐base). Materials and Methods A total of 135 zirconia crowns were designed with three different cement gap sizes: 20 µm, 30 µm, and ...

Thermal barrier coating by electron beam-physical vapor deposition of zirconia co-doped with yttria and niobia [PDF]
Journal of Aerospace Technology and Management, 2010 The most usual ceramic material for coating turbine blades is yttria doped zirconia. Addition of niobia, as a co-dopant in the Y2O3-ZrO2 system, can reduce the thermal conductivity and improve mechanical properties of the coating.
