  • The effects of LiF and CaF2 in the vitreous bond have been studied by the measurement of bonding strength. The results show that, the trend of CaF2 crystallization from Al-Si-O system vitreous bond is more obvious than that of LiF. The melting-point of the bonds is lower and the bonding force is stronger when using LiF than CaF2 as flux. The mole ratio (Al2O3+B2O3)/(R2O+RO+0.5LiF) can be used as a criterion to confirm the self-strength of the vitreous bonds.
