Yttria-stabilized zirconia is known to not be completely stabilized in the pure cubic YSZ phase up to temperatures above 1000 °C (Ref. and publications therein), commonly used abbreviations in conjunction with yttria-stabilized zirconia are: The thermal expansion coefficients depends on the modification of zirconia as follows: By the addition of yttria to pure zirconia (e.g., fully stabilized YSZ) Y ions replace Zr on the cationic sublattice. Thereby, oxygen vacancies are generated due to charge neutrality: formula_4 with formula_5, meaning two Y ions generate one vacancy on the anionic sublattice. This facilitates moderate conductivity of yttrium stabilized zirconia for O ions (and thus
Cubic zirconia diamond: Cubic zirconia, as a diamond substituent and jewel competitor, has been seen as a potential solution against conflict diamonds and the controversy surrounding the rarity and value of diamonds. Regarding the latter, the main argument presented being that the paradigm where diamonds were seen as rare due to their visual beauty is no longer the case and instead has been replaced by an artificially rarity reflected in their price. This is attributed to confirmed evidence that there were price-fixing practices taken by the major producers of rough diamonds, in majority attributed to De Beers Company known as to holding
