Graphite GL-1 (GOST 5279-74) is a natural mineral that has many unique properties, fire resistance, electrical conductivity, chemical resistance, low hardness, ductility, fat content, non-stick, diamagnetic. GL-1 graphite is obtained from graphite ores and is used in various industries, such as metallurgy, mechanical engineering, oil production, iron foundry, and steelmaking. The main quality indicators of GL-1 graphite are determined by the carbon and ash content; the higher the carbon and lower the ash content, the higher the quality of GL-1 graphite.
| Naming of indicators | Norm for GL-1 |
| Ash content, % no more | 13 |
| Remaining on grid No. 16, % no more | 40 |
| Mass fraction of moisture, % no more | 1.0 |
Scope of application: auxiliary material in the metalworking, iron and steel industries. Foundry paints. When drilling wells in the oil and gas industry.
