Scandia-stabilized zirconia doped with yttria: Synthesis, properties, and ageing behavior

Structure and conductivity of yttria and scandia‐doped zirconia crystals grown by skull melting

“…The 10Sc1YZ sample has the highest ionic conductivity and the conductivity of 9Sc3YZ samples was minimal. 9,14,47,50,51 In according with these studies the introduction of Y 2 O 3 decreases the conductivity of ScYSZ at high temperatures as the yttria/scandia ratio increased. It can be seen that the addition of Y 2 O 3 affects the solid solution conductivity different ways and depends on the Sc 2 O 3 content in the starting composition.…”

“…[8][9][10] One method to improve the properties of the electrolyte materials, such as to stabilize the cubic modification, to suppress conductivity degradation is the introduction of second dopant (co-dopant) in addition to Sc 3+ into the electrolyte structure. CeO 2 , 11-13 Y 2 O 3 , 9,14 Yb 2 O 3 , 13,15 Gd 2 O 3 12,13 , and Sm 2 O 3 13 were used as co-dopants.…”

Stabilisation dopant-dependent facilitation in ionic conductivity on millimeter-wave irradiation heating of zirconia-based ceramics

“…The 12 mol% scandia-stabilised zirconia under MMW irradiation heating showed maximum ionic conductivity among the zirconia-based oxide ion conductors reported in the literature, as shown in Fig. 5 [15,16]. This optimum compositional shift was attributed to the effect of MMW on the transfer and dissociation energies.…”

“…Fig. 2 shows a comparison of the ionic conductors, based on zirconia heated by a conventional furnace and MMW irradiation heating; the conductivity of all of the cation-substituted zirconia ceramics were enhanced by MMW irradiation by several to several tens that of the conventionally heated samples, as shown in the figure. MMW-irradiated ScSZ demonstrated the highest ionic conductivity value for zirconia ceramics reported to date [15,16].…”

Status and future trends in suspension spray techniques

“…However, these materials often show quite complex thermodynamic behavior, phase instabilities, etc., often leading to a loss of the desired advantageous properties (Spirin et al, 2012).
