FABRICATED METHOD OF LOW MELTING POINT GLASS, COMPRISED METAL OXIDE UTILIZING BY A REDUCTANT

摘要

PURPOSE: A method for manufacturing a low melting point glass is provided to allow glass to be manufactured at the temperature lower than the melting point in atmosphere by inhibiting the oxidation of metal components in air. CONSTITUTION: A method for manufacturing a low melting point glass comprises the step of putting a glass frit and a reducing agent into a box-type electrical furnace using an alumina crucible and melting them at 900°C ~ 1100°C. The reducing agent is sucrose. The ratio of the sucrose and the glass frit is 0.01~0.1:1. The glass frit comprises 25-50 mole% of P2O5, 2.5-25 mole% of R2O3 (wherein R is B, Al, Bi), and the balance of SnO2.
