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.

Abstract: A containment tube includes a sealed tube comprising silicon carbide, first and second ends, an inner bore extending along at least a portion of its axial length between the first and second ends, and contains a radioactive material within the bore of the sealed tube. The first end has a plug residing in the inner bore to close the first end, and the second end has a distal wall that closes the inner bore at the second. At least one of the first or second ends is bonded to the sealed tube by a sinter bond.

Abstract: A sintered ceramic article includes a silicon carbide tube and a silicon carbide base component circumscribing at least a portion of the tube and sinter-bonded to the tube. The sinter bond between the tube and the base component is defined as an interface bond and includes no bond materials. The interface bond has at least one of the following performance characteristics: a Shear Strength not less than about 25 MPa, a Nitrogen Seal Performance of not greater than 10%, a Helium Seal Performance of not greater than 10%, and/or a Vacuum Seal Performance of not greater than 10%.
