Abstract:
Provided is a super low melting SnO—SnF2—P2O5-based glass frit for which the firing temperature can be set to 200° C. or less and which has high water resistance and transparency. The fluorinated tin-based glass frit includes, in mol %, 30 to 70% of SnF2, 10 to 30% of P2O5, 10 to 40% of SnO, 0.1 to 10% of SnO2, 0 to 5% of In2O3, 0 to 5% of B2O3, and 0 to 5% of SiO2, and has a glass transition point of 160° C. or lower, a softening point of 180° C. or lower, and a maximum particle size of 100 μm or less. The fluorinated tin-based glass frit has a visible light transmission rate of 80% or more at 200° C. and a thickness of 0.6 mm of a fired product thereof, and a rate of volume reduction of the fired product due to soaking in hot water at 85° C. for 24 hours is 2 vol. % or less.
