1. A method, comprising:
forming an article that includes a first ceramic composite substrate, a second ceramic composite substrate, and a pre-sintered ceramic interface between the first second ceramic composite substrates, wherein the pre-sintered ceramic interface comprises a plurality of ceramic particles and a plurality of fibers; and
sintering at least a portion of the pre-sintered ceramic interface by heating the portion of the pre-sintered ceramic interface to a sintering temperature of the ceramic interface using joule heating to join the first and second substrates, wherein the sintering temperature is greater than about 1000 degrees Celsius (° C.).
