Kind Code:
A1
Abstract:
When silver powder is produced by using a reducing agent according to a wet reduction method, the present invention has no risk of fire by washing insoluble organic materials generated after a silver powder precipitation reaction with an aqueous solution comprising alkali metal borohydrides, is capable of increasing cleaning efficiency at low costs, reduces aggregation of the silver powder to be produced, and reduces the content of residual alkali metals. Accordingly, it is possible to provide silver powder having improved physical properties.
