摘要：

Lanthanum chromate ceramics with high brittleness, and difficult in deformation are difficult to process. Large ceramic components with complex shapes can be fabricated at low cost by ceramic joining technique. The lanthanum chromate precursor slurry was used as the interlayer material, and the lanthanum chromate ceramic was joined by spark plasma technique. Then the bonding strength of the joint was measured. The influence of joining temperature and holding time on the strength of the joint was analyzed by SEM, EDS, etc. The results show that the highest joining strength can be obtained at 1400 degrees C, and the second phase Cr4O5 appears in the parent material during the joining process.
