Overview
Amorphous Graphite 70 is a naturally occurring form of graphite characterized by its earthy or powdery texture and a carbon content of around 70%. Unlike flake or crystalline graphite, it lacks a well-defined crystalline structure, making it less pure but more cost-effective for certain industrial uses. It is mined from deposits worldwide, with significant sources in China, Mexico, and the United States. This type of graphite is prized for its versatility and affordability. It is commonly used in applications where high purity is not critical, such as refractory materials and lubricants. Its ease of processing and compatibility with various industrial processes make it a popular choice for manufacturers seeking reliable performance at a lower cost.
Physical and Chemical Properties
Amorphous Graphite 70 exhibits excellent thermal and electrical conductivity, making it suitable for high-temperature applications. Its lubricating properties stem from the layered structure of carbon atoms, which allows for easy slippage between layers. The material is chemically inert, resisting reactions with most acids, alkalis, and solvents. The density of amorphous graphite is lower than that of crystalline forms, typically ranging between 2.0 and 2.2 g/cm³. Its melting point is extremely high, around 3650°C, though it sublimes rather than melts. The material is insoluble in water and most organic solvents, ensuring stability in diverse environments. These properties make it ideal for use in harsh industrial conditions.
Main Applications
Amorphous Graphite 70 is widely used in the production of refractory materials, where its high thermal stability and resistance to thermal shock are critical. It is a key component in crucibles, ladles, and furnace linings for metal casting and glass manufacturing. The material's lubricity also makes it valuable in brake linings and clutch facings. In the battery industry, it serves as a conductive additive in electrodes, enhancing performance in lithium-ion and alkaline batteries. Additionally, it is used in foundry facings to improve mold release and surface finish. Other applications include pencil leads, paints, and coatings, where its black pigment and stability are advantageous.
Safety and Storage
While Amorphous Graphite 70 is non-toxic, prolonged exposure to its dust can cause respiratory irritation. Workers should use protective equipment such as masks and gloves to minimize contact. The material is not flammable but should be stored away from strong oxidizers to prevent potential reactions. Storage conditions should prioritize dryness and ventilation to prevent moisture absorption, which can affect performance in certain applications. Bulk storage in sealed containers or silos is recommended to maintain quality. Proper handling and disposal practices ensure safety and environmental compliance.
B2B Procurement Guide
When procuring Amorphous Graphite 70, buyers should verify the carbon content, typically around 70%, and assess the particle size distribution to ensure suitability for their specific application. Impurities such as ash and sulfur should be minimized, especially for high-performance uses like batteries or refractories. Price negotiations should consider bulk purchase discounts and shipping costs, as graphite is often transported in large quantities. Suppliers with certifications for quality and environmental standards (e.g., ISO) are preferable. Sampling and lab testing are recommended before large-scale procurement to confirm material consistency and performance.
