Graphite, natural & synthetic |
We offer both Natural as well as Synthetic Graphites. Natural Graphites are available in flake and needle form. The minimum carbon content can be fixed anywhere between 75% and 99.5%. Thermal conductivity: 8-17 W/mK (at 20°C) Many different particle size distributions are available. Synthetic Graphites are made from new pure electrodes with an extremely low SiO2 level and a sulfur content of less than 0.05%. Thermal conductivity: 40-130 W/mK (at 20°C) Many different particle size distributions are available, but the most common grades of Synthetic Graphite are:
Both Natural as well as Synthetic Graphites are mainly used for their lubricity, e.g. in: friction materials, solid lubricants, carbon brushes, pencils, crucibles, chemical insulation, electrodes. |
