Description

Carbon (Graphite) CAS NO 7782-42-5 is an allotrope of carbon characterized by its layered, hexagonal lattice structure, offering a unique combination of thermal stability, electrical conductivity, and lubricity. This material is critical for applications requiring high-temperature resistance, chemical inertness, and reliable performance under extreme conditions. It is an essential industrial material for sectors including metallurgy, energy storage, and advanced manufacturing.

Application

• Refractories & Metallurgy: Key component in crucibles, molds, and linings for high-temperature metal processing (e.g., steelmaking).
• Electrodes & Electrical Components: Used in batteries (e.g., lithium-ion anodes), fuel cells, and as electrodes in electric arc furnaces.
• Lubricants & Coatings: Serves as a dry lubricant in high-temperature or vacuum environments and in anti-seize compounds.
• Advanced Composites: Reinforcement material in polymer composites for aerospace and automotive parts requiring strength and lightweight properties.
• Gaskets & Seals: Used in flexible graphite sheets for high-temperature sealing applications in chemical processing.
• Pencils & Writing Instruments: The "lead" in pencils is primarily composed of graphite mixed with clay.
• Nuclear Reactors: Acts as a moderator and reflector in certain types of nuclear reactors.
• Foundry Facings: Applied as a mold wash to improve surface finish of metal castings.

Quality Control

Our graphite products are manufactured and tested under strict quality management systems to ensure batch-to-batch consistency and performance. We offer various grades, from industrial flake to high-purity synthetic graphite, each with defined specifications for parameters such as carbon content, ash content, particle size distribution, and density. A Certificate of Analysis (COA) detailing these parameters is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. Graphite powder should be stored to minimize dust generation and accumulation.
