Abstract (en)
[origin: WO0212123A1] The invention concerns a zirconia in fine powder form, a zirconia hydroxycarbonate and their methods of preparation. The zirconia has a chlorine content of more than 300 ppm and a sulphur content of more than 30 ppm and is in the form of a powder consisting of medium-size agglomerates of at least 1.5 mu m capable of being broken down into medium-size aggregates ranging between 0.1 mu m and 0.6 mu m. The zirconia hydroxycarbonate has the same chlorine and sulphur contents and is capable of resulting, after calcination, in a zirconia having the above-mentioned characteristics. The inventive zirconia can be used in particular in the manufacture of condensers of oxygen probes or for preparing catalysts.
