Unique Product with High Purity and High Crystallinity at Micron Levels from 1 to 100

Since 1986 when the first powder plant was established, SEC CARBON has provided fine powder that plays a role in our business with its extremely high purity and excellent high crystallinity. A wide range of series has been offered at micron levels from 1 to 100, so that customers can make their own choices according to their use. Our powder products include the one that has a 99.999% of super-high purity (five nines). As times advance, SEC CARBON fine powder is being actively utilized in diverse industries for such things as paint, sliding materials, metallurgic uses, and batteries.

Precise Manufacturing Process for Fine Quality Products

Integrated Pulverization Process Management

Fine powder is produced by an integrated production system from raw material treatment to finished products by fully utilizing the latest cutting-edge production equipment and our unique high-level machining technology. Under the consolidated manufacturing management, raw materials are pulverized to micron levels of 1 to 100 by ultrafine pulverization and classification equipment according to each desired usage. Through the classification process, the raw material is made into sophisticated products.

Strict Quality Control Systems and Continuous Technology Development

Stable grain size and consistent quality, these are the lifeline of fine powder. Fully-equipped with the latest and most-advanced inspection equipment, SEC CARBON repeatedly performs physical testing and analysis. In accordance with the unique and strict quality standards, SEC CARBON performs inspections consisting of the following three stages: the receiving inspection of raw materials, the in-process inspection conducted during each process, and the finished-product inspection. Aggressively working on technological development, our goal is to realize further high quality.

Measurement of Specific Surface Area

Product inspection by Electronic Microscope

Where is Fine Powder used ?: Used as raw materials for batteries and automobile paint; Fine powder is graphite powder with high purity. Through our unique research and development, this sophisticated product was developed. Until this advancement, conventional graphite powder products had difficulties in realizing uniform quality and stable supply. Our fine powder is actively being utilized in the latest cutting-edge industries, such as electrode materials of lithium-ion secondary batteries.
