Zirconium hydride an ore, usually a zirconium silicate, such as zircon. Zirconium is extracted from zirconium ore by removing the oxygen and silica. This process, known as the Kroll process, was first applied to titanium. The Kroll process results in an alloy containing hafnium. The hafnium and other impurities are removed in a subsequent step. Zirconium hydride is created by combining refined zirconium with hydrogen. Like titanium, solid zirconium dissolves hydrogen quite readily. The density of zirconium hydride varies based the hydrogen and ranges between 5.56 and 6.52 g cm. Even in the narrow range of concentrations which make up zirconium hydride,
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'.
