Abstract: The utility model discloses an integrated composite-layer saggar, comprising a saggar bottom and a saggar wall; the saggar bottom and the saggar wall at least comprise a substrate and an isolated layer positioned above the substrate for preventing high temperature diffusion of substrate substance to products inside the saggar, and the substrate of the saggar is integrally connected with the substrate of the saggar wall, the isolated layer of the saggar is integrally connected with the isolated layer of the saggar, the substrates use silicon carbide (SiC) material, and the isolated layers use inorganic oxide material. In the utility model, the silicon carbide material of the substrates is extended to the saggar wall from the bottom of the saggar, the strengthen of the saggar wall is increased, thereby avoiding saggar wall fracture and exfoliation such as breakage easily occurring in the use of the saggar and improving the thermal shock resistance of saggar by reasonably mounting expansion joints on the saggar bottom and the saggar wall, thus efficiently prolonging the service life of the sagger and improving the yield of electronic components when sintering.
