Problems solved by technology

However, since Nichrome-based metals contain Cr in the metal, there is a problem that a large amount of Cr melts out in the glass during melting to color the glass, and the melted Cr destabilizes the glass.

Abstract

Provided is a process for melting glass which enables long-period and repeated melting of SnO-P2O5 glasses, which glasses are liable to corrode a melting vessel made of platinum, and which little causes the deterioration of glass with constituents of a melting vessel even if the constituents thereof penetrate into molten glass in the melting step; and glass. [MEANS FOR SOLVING PROBLEMS] A process for melting glass by melting a glass raw material batch in a melting vessel, characterized in that the melting vessel is one made of zirconium or a zirconium alloy.

Description

technical field [0001] The present invention relates to a melting method of glass and glass, in particular to the sealing of electronic components such as various ceramic packages and magnetic heads, the sealing of various display devices, the partition of plasma display panel (PDP), the metal double wall of thermos bottle, etc. Layer container sealing and glass melting method and glass of various optical glass. Background technique [0002] Among the sealing materials used for electronic components such as ceramic packages and magnetic heads and display devices, it is required to be able to perform low-temperature sealing so as not to have adverse effects on components such as ICs and crystal oscillators, and it is also required that the coefficient of thermal expansion and the sealed material The coefficient of thermal expansion of the material matches. [0003] So far, as sealing materials satisfying these characteristics, various PbO-P 2 o 3 glass or a composite mater...
