Abstract:
      Lanthanum chromate ceramics with poor tensile properties, high brittleness, difficult deformation and high hardness is difficult to process. Large ceramic components with complex shapes can be fabricated at low cost by ceramic joining technology. In this paper, the lanthanum chromate precursor slurry was used as the interlayer material, and the lanthanum chromate ceramic was joined by spark plasma technology. And then the bonding strength of the joining was measured. The influence of joining temperature and holding time on the strength of the joint was analyzed by means of SEM, EDS and so on.
