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
Basque grammar rule which assigns focus to an element in pre-verbal position. The affirmative use of "ba-" (not to confused with the homophonous subordinating prefix meaning 'if') is normally used with synthetic finite forms, thus also "John badator" or "Badator John" 'John is coming' (as opposed to "John dator" " 'John" is coming'), "Badu dirua" (or in western Basque "Badauka dirua") 'She has money'. In most varieties of Basque, affirmative "ba-" is not so used with compound tenses or compound verbs, however. To place a compound verb form (or its affirmation) in focus, it may be enough to place the main sentence
