BISMUTH GLASS COMPOSITION, POWDER MATERIAL AND POWDER MATERIAL PASTE

Japanese Patent JP2016033094

A

PROBLEM TO BE SOLVED: To create a bismuth glass composition that can be fired at a temperature lower than or equal to 800°C even when containing no PbO, prevents the warpage of substrates and others and its peeling from substrates and others, and is resistant to erosion by a plating solution, and provide a powder material and a powder material paste.SOLUTION: A bismuth glass composition according to the present invention has a glass composition comprising, by mass%, BiO: 40 to 55%, SiO: 28 to 40%, ZrO: more than 5 to 9%, AlO: 2 to 10%, and BO: 0 to 5%, with the mass ratio (SiO+ZrO)/AlOof smaller than 15.SELECTED DRAWING: None
