Carbon Products Dept.
The chain of carbon products derived from coal has been a core business since the founding of the company in 1934. Various products are created to support domestic and overseas steel, auto, and other industries. In addition to coke for iron-making, carbon products derived from coal tar include needle coke for electrodes, pitch coke for carbon specialities, carbon black (CB), synthetic rubber (CB master batch), and so on.

Mitsubishi™ Coke is a raw material used in blast furnaces. The coke is manufactured by blending many types of coal and carbonized (coking) at a high temperature of about 1200 ℃ in a coke oven. Coke is one of the essential raw materials for iron-making in blast furnaces, and is supplied to major steel mills in Japan and other countries.
Needle cokes are used as a primary material for graphite electrodes in electric furnace. Coal-based needle coke is produced from coal tar that appears during coke production. Compared to petroleum-based needle coke, coal-based needle coke has excellent physical properties, such as low co-efficient of thermal expansion and low electric resistance, along with less spalling and less breakage. CAS No.94113-91-4
Pitch coke is produced from coal tar that appears during coke production. Pitch cokes are an essential raw material for building production equipment for semiconductor or solar array panel. It is also used as a raw material for the anode in aluminum smelting. CAS No.94113-91-4
MITSUBISHI™ Carbon Black is a black pigment that has been used in a wide range of fields such as newspaper ink, printing ink, colored resin, paint, toner, colored paper, India ink, and ceramics. Various grades of carbon blacks are available ranging from all- purpose grade to high-grade. In addition, our line of products includes industrial and environmentally-friendly carbon blacks.
