This series comes in a full lineup ranging from 1 micron for the standard grade to 100 microns for the ultrahigh-purity grade.

Grade	Features	Ash content (%)	Purity (%)	Real density	Interlayer spacing (Co/2nm)
SGP	This graphite powder is made by processing a carefully chosen raw material with our unique graphitization and high-purity treatment. It provides high electric conductivity and excellent lubricative characteristic.	0.03	99.97	2.24	0.3362
SGO	This graphite powder is made by our original method and resembles natural graphitic crystals in its high purity and orientation. Its electric conductivity, lubricative characteristic, and thermal resistance are comparable to those of flake graphite.	0.02	99.98	2.25	0.3360
SGX	This ultrahigh-purity graphite powder is purified by our high-purity treatment technology and its ash content is 10 ppm maximum.	10ppm	99.999	2.25	0.3360
SGL	This graphite powder is made by applying advanced graphitization to lump coke as a raw material. It has high abrasion resistance as well as excellent electric conductivity and lubricative characteristic.	0.25	99.75	2.20	0.3370

Main product applicable for the information and communication oriented society

Grade	Features	Ash content (%)	Purity (%)	Real density	Interlayer spacing (Co/2nm)
SGB	This globular graphite powder has been given an excellent crystalline structure by our original raw material and production method. It is most suitable as the material for the cathode of the secondary lithium iron battery.	0.07	99.93	2.21	0.3365

This graphite powder has achieved a high purity comparable to that of artificial graphite.

Grade	Features	Ash content (%)	Purity (%)	Real density	Interlayer spacing (Co/2nm)
SNO	This graphite powder is made by processing carefully chosen natural graphite with our special purification treatment. It has a purity level equivalent to that of artificial graphite and excellent electric conductivity and lubricative characteristic.	0.03	99.97	2.26	0.3355
SNE	This graphite powder is processed with our special flaking treatment and has even more excellent electric conductivity.	0.03	99.97	2.26	0.3355

This series is most suitable for sliding materials and graphite specialties.

Grade	Features	Ash content (%)	Purity (%)	Real density	Interlayer spacing (Co/2nm)
SCN	This graphitic material has a proper chemical reaction and an excellent sliding characteristic.	0.10	99.90	2.14	0.3375
SCL	This graphitic material is excellent in such a sliding characteristic as requires abrasive resistance.	0.40	99.60	2.05	0.3384
