Understanding Flake Graphite and Mesh Sizes
What is Flake Graphite?
Flake graphite is a type of natural graphite characterized by its layered structure and high carbon content. It is formed under high pressure and temperature conditions, resulting in a material with exceptional properties.
Properties:
- High Carbon Content: Flake graphite typically has a carbon content between 85% and 98%, making it highly conductive and chemically inert.
- Thermal Conductivity: It is an excellent conductor of heat, with thermal conductivity exceeding that of many metals.
- Electrical Conductivity: Flake graphite is one of the few non-metallic materials with high electrical conductivity.
- Lubricity: The flaky structure of graphite provides excellent lubrication, reducing friction and wear in mechanical applications.
- High-Temperature Resistance: Flake graphite has a melting point exceeding 3,600°C, making it suitable for high-temperature applications.
Applications:
- Battery Electrodes: Used in lead-acid, NiMH, and lithium-ion batteries to enhance efficiency and lifespan.
- Refractory Materials: Blended with clays to create refractory linings for furnaces in the steel and metal industries.
- Lubricants: Finely ground flake graphite is used as a dry lubricant in machinery, reducing friction and wear.
- Foundry Facings: Mixed with resins to create smooth finishes on cast metal parts.
- Pencil Leads: Compressed into rods for pencil manufacturing.
Mesh Sizes
Flake graphite is available in various mesh sizes, each with specific applications:
- +32 Mesh: Larger flakes suitable for applications requiring high lubricity and thermal conductivity.
- +50 Mesh: Medium-sized flakes used in refractory materials and battery electrodes.
- +80 Mesh: Finer flakes for specialized applications like lubricants and foundry facings.
- +100 Mesh: Very fine flakes for high-precision applications.
