PREPARATION OF YTTRIA-STABILIZED ZIRCONIA REACTION SINTERED PRODUCTS
A method of making a solid electrolyte-YSZ product, where the method includes the step of providing a powdered mixture of zirconia, yttria and about 2%, by wt., or less of a metal oxide, where yttria-stabilized zirconia is not added to the mixture. The method also includes sintering the powdered mixture at about 1500° C. or less, for about 5 hours or less, to form a reaction sintered YSZ. Also, a method of making a fuel cell electrolyte that includes the step of forming a green body that includes zirconia, yttria and about 2%, by wt., or less of a metal oxide, where yttria-stabilized zirconia is not added to the green body. The method also includes shaping the green body into a form of the electrolyte, and sintering the green body at about 1500° C. or less to form a reaction sintered yttria-stabilized zirconia and metal oxide electrolyte.
