Summary
Microparticles That Support Cutting-Edge Technology
These are fine silver particles that possess the highest electrical and thermal conductivity of any metal and are primarily used as conductive paste, electrodes for electronic components, and electrode materials for solar cells.
Mitsui Kinzoku through our proprietary wet reaction process, we provide ultrafine powders that combine high dispersibility, high loading capacity, and a sharp particle size distribution.
With a spherical shape and a smooth surface, and a uniform primary particle size, it can accommodate a wide range of particle sizes. You can also choose between hydrophilic and hydrophobic options.
