Influences of Fe2O3 on the structure and properties of Bi2O3–B2O3–SiO2 low-melting glasses

Bi2O3–B2O3–SiO2 glasses with the addition of Fe2O3 were prepared by a conventional melt quenching method. The effects of Fe2O3 addition on the structure, thermal behavior and chemical durability of resulting samples were studied. The CTE of the glass increased first and then decreased with increasin...

Description
Summary:Bi2O3–B2O3–SiO2 glasses with the addition of Fe2O3 were prepared by a conventional melt quenching method. The effects of Fe2O3 addition on the structure, thermal behavior and chemical durability of resulting samples were studied. The CTE of the glass increased first and then decreased with increasing Fe2O3 contents, whereas the tendencies of the Tg and Tf varied contrarily. No apparent effect on the structure of glasses with the increase of Fe2O3 contents was observed and the chemical durability of the glasses was significantly improved with the increase of Fe2O3 contents.
