dry graphite powder

Dry graphite powder is a versatile industrial material composed of pure carbon in a crystalline form. This fine, silky substance possesses exceptional properties that make it invaluable across various industries. The powder features a layered hexagonal structure that provides superior lubrication capabilities, high thermal conductivity, and excellent electrical conductivity. With particle sizes ranging from submicron to several microns, dry graphite powder can be precisely tailored for specific applications. The material exhibits remarkable chemical stability, remaining inert to most chemicals and maintaining its properties even at extreme temperatures. Its natural lubricating properties stem from its unique crystal structure, where carbon atoms are arranged in parallel layers that can easily slide over one another. This characteristic makes it an ideal dry lubricant for machinery, automotive parts, and industrial equipment. The powder also demonstrates outstanding heat resistance, capable of withstanding temperatures up to 3,000°C in non-oxidizing environments. Its high purity levels, typically ranging from 95% to 99.9%, ensure consistent performance across applications. The material's ability to form stable dispersions and its compatibility with various carrier materials makes it exceptionally versatile in manufacturing processes.

Superior Lubrication Performance

Superior Lubrication Performance

Dry graphite powder's exceptional lubrication capabilities stem from its unique layered structure, which enables smooth sliding between surfaces without the need for additional lubricants. This natural lubricity significantly reduces friction coefficients, typically achieving values as low as 0.1 under proper conditions. The powder forms a consistent and durable lubricating film that adheres well to metal surfaces, providing long-lasting protection against wear and tear. Its effectiveness as a dry lubricant is particularly valuable in applications where liquid lubricants are impractical or undesirable, such as in high-temperature environments or clean room operations. The powder maintains its lubricating properties across a wide temperature range, from cryogenic conditions to extreme heat, making it uniquely versatile in industrial applications. This consistent performance results in reduced equipment downtime, lower maintenance costs, and improved operational efficiency across various manufacturing processes.
Thermal and Electrical Conductivity

Thermal and Electrical Conductivity

The exceptional thermal and electrical conductivity of dry graphite powder makes it an invaluable material in numerous high-tech applications. With thermal conductivity values ranging from 25-470 W/m·K depending on grade and preparation method, it efficiently manages heat in critical systems. This property is particularly important in electronic devices, where heat dissipation is crucial for optimal performance and longevity. The powder's electrical conductivity, typically ranging from 10^2 to 10^5 S/m, enables its use in conductive coatings, electromagnetic shielding, and battery electrode materials. Its ability to maintain these properties under varying environmental conditions ensures reliable performance in diverse applications. The combination of thermal and electrical conductivity in a single material simplifies design considerations and reduces the need for multiple specialized materials in complex systems.
