An innovative method for joining materials at low temperature using silver (nano)particles derived from [AgO2C(CH2OCH2)3H]

▸ We achieved pressureless copper-to-copper silver joints at low temperatures. ▸ Enrichment of the silver layer with copper was possible. ▸ Formation of a molten metal-like silver phase was beneficial for joining. ▸ We report on the phase stages of different silver carboxylates. ▸ Formation of nanoparticles allows low temperature sintering.
