Abstract:
An extended length tube structure includes a first ceramic tube segment having a first end and a second end, and a second ceramic tube segment having a first end and a second end, in which the second end of the first ceramic tube segment is arranged to face the first end of the second ceramic tube segment. A ceramic coupling component is positioned to circumscribe the end-to-end configuration of the tube segments, and is sinter-bonded to the tube segments to form a continuous, extended length tube structure having a seal, such as a sinter bond or an interference bond, that is free of bond materials.

Claim (Index 16):
A method of forming an extended length ceramic tube structure, comprising:\n providing a first ceramic tube segment having a first end and a second end, providing a second ceramic tube segment having a first end and a second end; pre-sintering the first and second ceramic tube segments; surface cleaning an outer surface of each of the tube segments; providing an un-sintered or partially sintered ceramic coupling component; arranging the first and second tube segments and the coupling component such that the second end of the first ceramic tube segment faces the first end of the second ceramic tube segment, and the coupling component overlies the second end of the first tube segment and the first end of the second tube segment; and co-sintering the first and second tube segments and the coupling component to form a seal between the coupling component and each of the first and second tube segments.
