Composite particles and methods for producing them, composite particle compositions, bonding materials and bonding methods, and bonded products.

摘要

The method for producing the composite particles is as follows: step A) a step of mixing a metal salt and a reducing agent to obtain a metal complexing reaction solution, and step B) heating the metal complexing reaction solution to obtain the metal complexing reaction solution. The average particles include a step of reducing the metal ions in the metal ion to obtain a slurry of the composite particles, and at any timing from the step A to heating the metal complexing reaction solution in the step B. Metal particles or metal oxide particles having a diameter of 0.03 to 50 μm, and an organic metal compound selected from an alkali metal-based organic metal compound or an alkaline earth metal-based organic metal compound are added.
