Abstract

The chemical durability of Bi₂O₃ ternary glasses was measured by powder method (measuring method for chemical durability of optical glass). The glass powder was treated at 90C for 60 minutes in water. The chemical durability is the order of Li₂O>CaO=SrO>Na₂O>BaO. The electric field strength of cations is the order of Li₂O>CaO>SrO> BaO>Na₂O. It is apparent that the chemical durability corresponds with the electric field strength of cations. The reaction product was analyzed by XRD. The precipitate is only Bi₂O₃.
