Natural Flake Graphite

Physical and Chemical Properties of Natural Flake Graphite:
- High Temperature Resistance: Graphite is one of the most high-temperature resistant materials available. It can withstand temperatures up to 3800 °C. Even under ultra-high temperature arcs, graphite experiences minimal weight loss. At 2000 °C, its strength can double.
- Electrical and Thermal Conductivity: Graphite exhibits exceptional conductivity—hundreds of times higher than general non-metallic materials. Its thermal conductivity surpasses that of steel, iron, lead, and other metals. Interestingly, the thermal conductivity of graphite decreases with increasing temperature, and it remains in an adiabatic state even at extremely high temperatures.
- Lubricity: The lubricating performance of graphite depends on the size of its flakes. Larger flakes result in a smaller friction coefficient, leading to better lubrication performance.
- Chemical Stability: At room temperature, graphite demonstrates good chemical stability. It can resist corrosion from acids, alkalis, and organic solvents.
- Plasticity: Graphite possesses excellent toughness and can be milled into very thin sheets.
- Thermal Shock Resistance: When used at high temperatures, graphite can withstand drastic temperature changes without damage. Its volume remains relatively stable, preventing cracks during abrupt temperature fluctuations.
