Abstract

PURPOSE: To prevent defectives such glass cracks from occurring by specifying the crystal grain size of stem lead wires consisting of nickel.
CONSTITUTION: The crystal grain size of stem lead wires consisting of nickel ranges to the inside points of the section almost coinciding with a trapezoid which is formed by connecting each point of coordinates (C=0.01, G=4), (C=0.07, G=6), (C= 0.07, G=7.5), and (C=0.015, G=7.5) in a diagram whose Y axis shows their carbon content C and whose X axis their crystal grain size number G, respectively. As described, it is easier to control the crystal grain size than to control carbon content and the carbon content also covers a wide range than before. Consequently, the nickel wires for stem lead wires can easily be supplied.
