Abstract
Solid electrolyte on the basis of aluminum oxide with the addition of titanium dioxide which further comprises zirconium dioxide. The components should be used in the following ratio in percent by weight: ______________________________________ aluminum oxide 85-95 titanium dioxide 1-5 zirconium dioxide 4-10. ______________________________________ The advantages of the solid electrolyte according to the invention consists in elevated heat and slag resistance. Service life of these solid electrolytes is by at least 3 times longer than that of prior art solid electrolytes.
Claims5
