HOME > Products Line Up

- We manufacture Ag Powder for conductive paste or low-temperature firing.
- We also manufacture Pd Coated Ag Powder, which prevents a migration during fusing.
- Other size or spec are available under a co-development.

Others Under Development
We develop:
- Ag Nano-Powder capable of a use in forming circuit pattern for inkjet by a low temp. firing, which enables circuit forming with polymer-film state.

- Pt Nano-Powder capable of a use as an electrode catalyst of fuel cell,
which is gathering attention as 'Clean Energy'.

Characteristics of our powders are:
- Ag Nano-Powder 5-20nm particle size
- Pt Nano-Powder 4-10nm particle size
Both powders are monodispersed with sharp particle size distibutions.
