Abstract
A ceramic bonding material including at least one fibrous material, a flux agent and a thickening agent wherein the ceramic bonding material fired at a set temperature to bond the two adjacent substrate faces.
Claims20
A method for forming a cured ceramic structure comprising the steps of:
- (a) applying a bonding material to at least one bonding surface selected from a first bonding surface of a first substrate piece and a second bonding surface of a second substrate piece wherein the bonding material further comprises a fibrous material, a fluxing agent and a thickening agent wherein the fibrous material has a CTE that is substantially similar to the CTE of at least one of the first and second substrates;
- (b) joining the first bonding surface and the second bonding surface such that the bonding material is positioned between the first bonding surface and the second bonding surface to form a ceramic structure including an uncured bonding material;
- and
- (c) heating the ceramic structure at a temperature of from about 1,000° C. to about 1,600° C. for a time sufficient to form a ceramic structure including a cured bonding material.
