Abstract
Provided are fine coated copper particles, which are fine with a narrow particle size distribution and superior storability, and which can be sintered at low temperatures. Specifically provided is a method for producing fine coated copper particles which is characterized by including: a step of mixing a copper-containing compound and a reducing compound to form a composite compound that is capable of thermal decomposition to generate copper in an alkylamine; and a step of heating the composite compound in the alkylamine to produce fine copper particles coated with the alkylamine.
Claims6
A method for producing fine coated copper particles, comprising:
- a first step of mixing a copper-containing compound and a reducing compound to form a composite compound comprising the copper-containing compound and the reducing compound, that is capable of thermal decomposition to generate copper in an alkylamine;
- and
- a next step of heating the composite compound in the alkylamine to produce fine copper particles coated with the alkylamine.
