Zirconium dioxide coating on particles of titanium dioxide pigments, as a refractory material, in insulation, abrasives and enamels. Stabilized zirconia is used in oxygen sensors and fuel cell membranes because it has the ability to allow oxygen ions to move freely through the crystal structure at high temperatures. This high ionic conductivity (and a low electronic conductivity) makes it one of the most useful electroceramics. Zirconium dioxide is also used as the solid electrolyte in electrochromic devices. Zirconia is a precursor to the electroceramic lead zirconate titanate ("PZT"), which is a high-K dielectric, which is found in myriad components. The very low
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
