Title:
BRAZING FILLER METAL PASTE FOR JOINING ALUMINUM NITRIDE SUBSTRATE TO METALLIC PLATE
Document Type and Number:
Japanese Patent JPH0570262
Kind Code:
A
Abstract:
PURPOSE: To surely join an AlN substrate to a metallic plate at the time of joining with a brazing filler metal contg. an active metal and to improve the reliability of the resulting joined body.
CONSTITUTION: TiN powder is added to metal powders of Ti, Cu and Ag by about 1-10 pts.wt. per 100 pts.wt., in total, of the metal powders and an org. vehicle (org. substance) is further added to obtain brazing filler metal paste. When an AlN substrate is superposed on a metallic plate with the paste in-between and they are heat-treated, part of the TiN transfers to the interface between the metallic plate and the AlN substrate and the reaction of the Ti powder in the brazing filler metal with the AlN of the AlN substrate is accelerated.
