Using Zirconium to
Enrich the Future

Making the Exhaust Gas From Automobiles Cleaner

The surface area of our products for catalyst applications for one passenger car is roughly equivalent to the ground of the Koshien Stadium, approx. 13,000 m2
Precious metals are supported on the large surface keeping them at a distance from each other to prevent sintering with other precious metals even when exposed to high-temperature exhaust gas. Also, exhaust gas from automobiles contain different types of toxic substances *1 one that is required to be treated by oxidation and another that needs to be treated by reduction. Our products for catalyst applications repeat absorption and release of oxygen consistently to treat these toxic substances properly.

*1 Carbon monoxide (CO), Hydrocarbon (HC), Nitric oxide (NOx), and Particulate matter (PM)

Development and supply of positive electrode additive materials for secondary batteries

Zirconium compounds have a function to protect the positive electrode of lithium-ion batteries, and there are growing expectations for zirconium compounds to improve safety and durability of the batteries.
We have succeeded in refining the positive electrode additive materials to nanometers and are undertaking research and development aiming for the practical use in the next-generation all-solid-state batteries, as well as conventional liquid electrolyte batteries.
