Advanced Ceramics - fiber optic connectors
Zirconia Powders TZ Series - Supporting optic fiber networks
Using the latest hydrolysis processes and nano-technologies, Tosoh produces the TZ-Series of zirconia powders. Through complete control over materials and production processes, Tosoh can maintain consistent high purity and quality. For this reason The Tosoh zirconia is used in optical connector parts and precision tools.  

Sputtering Targets - flat-panel displays
Produced at our operating bases in Japan, United States, and Korea, Tosoh’s sputtering targets are available in a variety of high-purity metals, metal alloys, cermet and ceramic compositions.  Targets can be made in all shapes, sizes and purity levels to meet design specifications.  In communications, Tosoh’s sputtering targets are used for the production of semiconductors,
magnetic recording media (rigid disks, rewritable-optical disks), recording heads, thermal print heads, flat-panel displays and thin-film resistors.

Electrolytic manganese dioxide (EMD) - batteries
Tosoh has the largest battery-grade EMD capacity in the world. With manufacturing facilities in Japan and Greece, Tosoh is able to meet the most demanding requirements of our customers. EMD keeps the communications revolution moving with the production of dry cells and soft ferrites.
