| Abstract | A CaO-Al2O3-SiO2 system glass ceramic with addition of Li2O and Fe2O3 was developed to join alumina ceramics. The crystallization behavior of the glass interlayer during joining process was investigated by DTA, SEM and XRD. The effect of joint microstructure and phase composition on the joint strength was study. The results show that LiAlSi2O6, CaSiO3, Ca3Fe2Si3O12, and CaAl2Si2O8 are formed in the glass during conventional crystallization treatment. However, when the glass was used to join alumina, the crystallization behavior of the glass interlayer is closely related to the heating cycle. Direct cooling from joining temperature leads to completely amorphous interlayer formation, due to the absence of enough nucleation driving force. An extra nucleation-crystallization treatment during cooling contributes to crystallization of the glass interlayer in joints. Meannhile, the phase composition of glass interlayer can be adjusted by changing the crystallization temperature according to the DTA results. In addition, the joint strength is highly sensitive to crystalline phases in the interlayer. When there is only CaAl2Si2O8 formed in the interlayer, the joint strength reaches as high as 247.5 MPa. By contrast, when there is LiAlSi2O6 or Ca3Fe2Si3O12 formed in the interlayer, the joint strength is only 10-135 MPa. |
