Abstract
The invention is directed to effective means for joining materials having dissimilar coefficients of thermal expansion, such as advanced ceramics with metallic compounds. Moreover, the present invention relates to furnace tubes and methods of fabricating a joint between two different materials, which is compositionally graded to provide a substantially graded coefficient of thermal expansion between the joint materials.
