Method for bonding refractory ceramic and metal

A method for mechanically bonding a metal component to a ceramic material, comprising:

• a. providing a metal component comprising an anchor material attached to at least a first portion of one surface of the metal component;
• b. providing a ceramic material having a first surface and a second surface, wherein the ceramic material defines at least one conduit extending from the first surface to the second surface, wherein the at least one conduit has a first open end defined by the first surface, a second open end defined by the second surface, a continuous sidewall, and a cross sectional area;
• c. positioning the ceramic material such that at least a portion of at least one of the first open end and the second open end of the at least one conduit is in overlying registration with at least a portion of the anchor material;
• and
• d. applying a castable ceramic bonding agent into at least a portion of the at least one conduit from the first surface of the ceramic material such that at least a portion of the castable ceramic bonding agent flows in at least one of following manners:
• (1) through;
• (2) around;
• and (3) over at least a portion of the anchor material located at an opposing end of the at least one conduit, and wherein the first surface of the ceramic material is an exterior surface;
• and
• e. solidifying the castable ceramic bonding agent to form a mechanical bond which is capable of enduring temperatures above 1400° C.;
• wherein the metal component comprises at least one noble metal and noble metal alloy thereof, at least one platinum group metal and platinum group metal alloy thereof, or a combination thereof, and
• wherein the castable ceramic bonding agent is capable of enduring temperatures above 1400° C.
