<p>A zirconium oxide ceramic suitable for use as an electrolyte which contains a zirconium oxide, a stabilizing oxide (such as, yttrium oxide, ytterbium oxide or calcium oxide), aluminum oxide and ferric oxide in an amount from about 0.9 to about 5 volume % by volume of aluminum oxide present. A preferred composition being from about 67.5 to about 75 volume % zirconium oxide by total volume, aluminum oxide in the range of about 10 to about 14.9 volume % by volume of the total volume; yttrium oxide in the range of about 19.5 to about 25 volume % by volume of the zirconium oxide, and ferric oxide in an amount from about 0.9 to about 5 volume % by volume of aluminum oxide.</p> |
