| Nickel Ultra Fine Powder
Supporting IT and Mobile Revolution
|
Along with the rapid development of information
networks, small-sized and lightweight electronics components
are now playing an increasingly pivotal role in the IT revolution.
This development of small-sized and lightweight components for
the most advanced products is supported by new fine materials.
We developed nickel ultra-fine powder in 1995, and the demand
for this new product has rapidly been increasing as a material
for internal electrodes in multi-layer ceramic capacitors. Ceramic
capacitors are important electronic components that are used
with diodes to convert AC（alternative current）to DC（direct current
）or to eliminate high-frequency signal noises. For example,
more than 250 multi-layer ceramic capacitors are used in a mobile
phone.

| Nickel
ultra fine powder with a high purity of 99.9 percent
or more is adopted in the manufacture of multi-layer
ceramic capacitors for mobile phones, notebook
PCs,and PDAs, all of which must be small, lightweight
and thin. |

| 1. Manufacturing method: CVD method |
| We have succeeded in the development of nickel
ultra-fine powder for the first time in the world using a chemical
vapor deposition (CVD) method. In this process, nickel chloride
is heated, vaporized, and allowed to react with hydrogen to
produce nickel ultra-fine powder. |
