Apparatus for fabricating composite ceramic members

Creators

Description

Methods and apparatus for fabrication of composite ceramic members having particular application for measuring oxygen activities in liquid sodium are described. The method involves the simultaneous deposition of ThO2: 15 percent Y2O3 on a sintered stabilized zirconia member by decomposition of gaseous ThCl4 and YCl3 and by reacting with oxygen gas. Means are provided for establishing an electrical potential gradient across the zirconia member whereby oxygen ions, from a source on one side of the member portion to be coated, are migrated to the opposite side where a reaction and said decomposition and deposition are effected
