As global interest in environmental issues rises, so does demand for automotive exhaust system components such as Diesel Particulate Filter (DPF), and holding mat (MAT) for the catalytic monolith made by ceramics. DPF, which can trap 99% or more of the black smoke emitted by diesel engines, has grown as a standard component of the industry due to its performance and reliability. Now, the environmental regulation become stricter and the market for automotive exhaust system components is expected to grow further. Therefore, as the leading company of DPF and MAT, we will continue to develop high-performance products and to reduce damage to the environment.

These are products made of graphite, which meets a diverse array of needs in industry as a fine material that features the properties both of metals and of ceramics. Made through full use of material technology, high-precision machining technology, high-purity purification technology, and surface-treatment technology, graphite products are contributing to the growth of leading-edge industries of every type as materials for semiconductor fabrication equipment, electrode materials for electric-discharge machining use, next-generation products for the energy industry, and more.

These fine-ceramics products have been developed based our own innovative high-temperature electric-furnace technology arising from compoundingβsilicon carbide powder, and making use of integrated technologies extending from raw materials to sintered bodies.
These products find use in semiconductor manufacturing equipment and other fields demanding resistance to corrosion and high precision.

Development proceeded apace for "IBI-Wool" ceramic fiber, which makes use of the electric-furnace technology that we have amassed over many years. Offering excellent heat resistance and insulating performance, this is available as both material and formed products, and is widely used in industrial products such as sintered bodies and fuel cells.
