Latest Patents

Ochi's latest patents include a method for producing silver powder and a conductive resin composition. The first patent describes a silver powder containing dendrite silver particles, characterized by a unique dendrite shape with one trunk and multiple branches. The thickness of the trunk ranges from 10 to 280 nm, and the branches per length of the trunk vary from 6 to 30 branches per micrometer. Notably, at least 50% of the silver particles are dendrite silver particles. This silver powder is produced through the electrolysis of an electrolyte solution containing silver ions and hydantoin or its derivatives.

The second patent focuses on a novel silver-coated copper powder, which features a dendritic shape and enhanced electrical conductivity without the need to increase the silver content. This innovative powder consists of silver-coated copper particles, with a silver layer that may include nitrogen, maintaining a nitrogen content of 0.2 to 10.0 parts by mass relative to 100 parts by mass of the silver content.
