摘要: 通過抗彎強度測試研究了LiF和CaF₂對陶瓷結合劑性能的影響.結果表明在Al-Si-O系陶瓷結合劑中,CaF₂的析晶現象明顯大于LiF.以LiF為助溶劑的陶瓷結合劑比用CaF₂為助溶劑的陶瓷結合劑熔點低、粘接強度大.當以LiF為助熔劑時,可以用摩爾數比值（Al₂O₃+B₂O₃）/（R₂O+RO+0.5LiF）判斷陶瓷結合劑自身的強度.

Abstract: 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.
