CSR(Corporate Social Responsibility):For the Sustainable Future

Exploration of Various Possibilities

Tanaka Kikinzoku Group has continuously pursued the potential of precious metals based on its creative technological abilities.
We make use of the excellent properties of precious metals in a wide range of industrial fields to support various technological innovations for the creation of a sustainable future.

Potential of Precious Metals

Composed of the eight elements of platinum, gold, silver, palladium, rhodium, iridium, ruthenium and osmium, precious metals are materials with infinite possibilities and various properties such as high resistance to chemicals, corrosion resistance, high conductivity, high ductility, thermal resistance and catalytic actions. Under the slogan of“ Mastering Precious Metals,” the Tanaka Kikinzoku Group has been committed to the research and development, stable supply and recycling of products that make effective use of the properties of precious metals based on its technologies improved over many years. Through business activities that unlock the potential of precious metals, we will try to develop and provide products that help solve environmental and energy issues and contribute to the creation of a prosperous society and a beautiful future for the Earth.

Industries and Technological Innovations

○Precious Metal Precursor for CVD/ALD

With the widespread use of smart devices and progress in computerization in recent years, there has been constant demand for the improvement of the performance of semiconductors and the reduction of their cost. In the commercialization of leading-edge semiconductors, such innovations require the discovery of new processes and new excellent materials. In particular, for the refinement of semiconductor devices, the development of new materials is an urgent task and processes using precious metals are also proposed.
Tanaka Kikinzoku Kogyo K.K. is committed to the development of precious metal precursors for CVD/ALD used to form thin films of ruthenium, which has excellent chemical and electrical properties, as well as platinum, iridium, etc. We will design and develop precious metals precursors that help improve the performance of advanced semiconductors and reduce the cost based on our original recycling techniques so that we can contribute to technological innovations for information society through semiconductor devices.

○Fuel Cell (FC)

Fuel cells are becoming more widespread on a global scale towards the creation of a hydrogen-based society. Tanaka Kikinzoku Kogyo K.K. has worked for the development of fuel cell electrode catalysts for many years. Its shipments of electrode catalysts for polymer electrolyte membrane fuel cells (PEFCs) are among the largest in the world.
Being small, lightweight and high-power, PEFCs are used for fuel cell cars, residential-use fuel cell "ENE-FARM," etc., and demand for them is expected to increase. Accordingly, in January 2019, we significantly enhanced the production abilities of FC Catalyst Development Center, our R&D and production base for electrode catalysts.
We also exhibited fuel cell electrode catalysts, along with electrode catalysts for water electrolysis, which are necessary for hydrogen production, palladium hydrogen permeable films, which realize high-purity hydrogen purification, and other items in FC EXPO 2019, one of the world's largest fuel cell trade shows held in Tokyo from February to March 2019. We will work for the research and development and stable supply of products that help create a hydrogen-based society.

○Operations and Treatment with Less Physical Burden

In the medical field, in response to the need for treatment with less physical burden, therapeutic techniques using catheters are evolving to minimize anesthesia and skin incision. The instruments used in catheter therapy such as guide wire and stent, as well as markers that indicate their positions in the body, require in vivo safety and high visibility under radioscopy. To achieve those properties, precious metals such as platinum, gold and iridium are considered to be suitable as the materials.
Tanaka Kikinzoku Kogyo K.K. is committed to the development of platinum materials for such medical indwelling devices based on the high purity and quality of precious metals and its fine processing techniques. For the practical use of products that can properly and quickly meet the needs in the clinical field in Japan, we are promoting development through a business-academia collaboration with School of Medicine, Tokai University. We would like to contribute to the improvement of people's health and welfare, such as their quality of life (QOL), through the development of precious metals for the medical field.
