Wetting and joining of surface-oxidized SiC ceramic with calcium lithium aluminosilicate glass filler

Joining SiC ceramics with ZrSi2–SiC filler at low temperatures

“…15 In addition, ZrSi 2 is considered as a candidate material for nuclear energy application due to its low neutron cross-section. 16 However, the difference in thermal expansion coefficient between ZrSi 2 (8.3 × 10 −6 / • C) 17 and SiC (4 × 10 −6 / • C) 18 ceramics could lead to the generation of a high residual stress in the joint after cooling, which potentially weakens the mechanical performance of the joint. Generally, materials with low thermal expansion coefficient can be added to reduce the thermal expansion coefficient mismatch between the interlayer and the substrate [19][20][21] in order to improve the joint performance.…”

Joining of SiC Ceramic by Si–C Reaction Bonding Using Organic Resin as Carbon Precursor

“…The joining technology is an effective way to realize complex-shaped or large SiC ceramic parts. A wide range of methods have been reported to join SiC ceramics, such as metallic braze-based joining [5], the use of MAX phases [6], diffusion joining [7], polymerderived SiC joining [8], glass-ceramic joining joint [9], and Si-C reaction joining [10][11][12][13][14][15][16][17][18]. Among these methods, Si-C reaction joining is an attractive technique because the thermomechanical properties of the joint interlayer can be tailored to match those of the joining materials [16].…”
