Fiber optic connectors and precision tools

Advanced ceramics

Tosoh's TZ series of zirconia powders, produced using the latest hydrolysis processes and nano-technologies, are known for consistent high purity and quality. Complete control over materials and production processes results in Tosoh zirconia that supports optic fiber networks with higher performing optical connector parts and precision tools.

Consumer and industrial products manufacturing

Sputtering targets

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

Production of batteries for electronic devices

Electrolytic manganese dioxide (EMD)

EMD is used in the production of dry cells and soft ferrites. Produced in Japan and Greece, Tosoh EMD is critical to the communications industry, meeting the most demanding requirements of manufacturers throughout the world. Tosoh has the largest battery-grade EMD capacity in the world.

Rechargeable lithium-ion batteries

Electrolytic manganese dioxide (EMD)

Rechargeable lithium-ion batteries are expected to become mainstream in electric, hybrid, plug-in hybrid, and other eco-vehicles. The lithium manganese oxide (LMO) used for their cathodes demonstrates superb safety because of its stable chemical structure. EMD is one of the raw materials used in producing LMO.



Tosoh develops and manufactures the key ingredients used in products that form the backbone of the world’s modern communications infrastructure, from semiconductors and optic fiber networks to magnetic recording media, batteries and flat-panel displays.
