| 摘要 |
This invention relates to solutions for use in the fusion or bonding of one metal to another. One metal is present in solid form, the other in a dissociable form in solution. Broadly, the solutions are aqueous, have a pH of about 0.4-14, a conductivity of 10 to 80 ohms cm and contain: (1) a compound consisting of a dissociable polyvalent metal to be fused to the other metal; (2) a compound which is capable of complexing with compound (1), compounds (1) and (2) being either soluble in water or forming a complex which is soluble in water; (3) a stabilizer which functions to keep (1) and (2) and the complex thereof in solution; and (4) a catalyzer which functions to promote the speed of reaction and reduce the valency of the polyvalent metal to a lower valence and to catalyze the complexing action between (1) and (2). |
