GLASS COMPOSITION

摘要

Provided is a glass composition that is characterized by including at least two alkali earth metal oxides from among SiO2, B2O3, Al2O3, ZnO, CaO, MgO, and BaO, and by substantially not including Pb, P, As, Sb, Li, Na, or K. Like the "glass material comprising mainly lead silicate" used in the prior art, the glass composition of the present invention can be used for a variety of uses, such as semiconductor junction protection, but employs a glass material that does not contain lead. In addition, as the glass composition contains at least two alkali earth metal oxides from among CaO, MgO, and BaO, the value of the average linear expansion coefficient occurring in the range of 50-550° C is close to the value of the linear expansion coefficient of silicon, thereby making it possible to use the glass composition for a variety of uses, such as semiconductor junction protection.
