COMPOSITION FOR METAL BONDING

摘要

PROBLEM TO BE SOLVED: To provide a composition for metal bonding capable of removing an oxidized film on a surface of base metal and bonding metals to each other. SOLUTION: A composition for metal bonding is composed of metal particles and a hydrocarbon compound which C-H bonding and dissociation energy is below 950 KJ/mol. When heating up with the composition for metal bonding between metals to be bonded, the hydrocarbon compound forms a radical state in which hydrogen is separated and deoxidizes the oxidized film of the metal surface to be bonded. Therefore, metals are bonded in good condition through the intermidiary of the metal particles.
