Pure Graphite Rod

Pure Graphite Rod is manufactured from high-purity graphite materials through controlled forming, purification and machining processes. It features excellent thermal stability, electrical conductivity and chemical resistance, making it suitable for demanding high-temperature industrial environments. 

Maintained low ash content typically < 2 ppm to help minimize material contamination in sensitive, high-temperature thermal processes and advanced material synthesis.

Exhibited flexural strength ranging from 35–55 MPa to assist in effectively resisting severe mechanical stress and thermal shock inside industrial furnaces.

Processed with high-purity petroleum coke to support consistent electrical conductivity and uniform thermal performance across batches.

Offered stable bulk density between 1.75–1.92 g/cm³ to help lower oxidation rates and extend component lifespan during extended operational cycles.

High resistance to acid, alkali, and corrosive solutions, significantly reducing chemical erosion in aggressive industrial and chemical processing applications.

Diameter Range: Standard and custom diameters available from 10 mm up to 500 mm.

Length Options: Precision cutting and machining available up to 2000 mm or based on specific project blueprints.

Anti-Oxidation Treatments: Optional impregnations and specialized antioxidant coatings are available to significantly reduce consumption rates when rods are exposed to air at elevated temperatures.

Vacuum & Heat Treatment Furnaces: Utilized as heating elements, structural supports, nuts, bolts, and thermal insulation shields.

Semiconductor & Photovoltaic Industry: Applied in crystal growth equipment and high-purity thermal components where contamination control is critical.

Chemical Engineering: Used for corrosion-resistant heat exchangers, electrodes, and chemical reactor linings.

Electrical & Mechanical Fields: Applied in sliding contacts, brushes, and specialized mechanical sealing elements.

For High-Vacuum Thermal Applications: Opt for our highest-purity grades (< 2 ppm) with standard density to prevent outgassing and avoid semiconductor crystal contamination.

For High-Oxidation or Air-Exposure Environments: Highly recommended to select our customized anti-oxidation impregnations or coatings to extend rod operational lifespan at elevated temperatures.

Engineering Consultation: Need assistance matching material specifications to your furnace operating temperature or mechanical load? Contact our senior materials engineering team for custom technical support.

Preventing Oxidation: For non-vacuum or CO₂ atmospheres above 400°C, use anti-oxidation coatings or maintain an inert gas (Ar/N₂) purge to prevent surface consumption.

Managing Thermal Shock: Implement controlled heating ramp rates during initial startup cycles in high-power vacuum furnaces to minimize internal stress and avoid cracking.

Controlling Contact Resistance: Regularly inspect electrical connection points and clean accumulated debris to ensure uniform conductivity and prevent localized overheating.

Protection: Wrapped in moisture-proof inner film, cushioned with thick pearl cotton/bubble wrap, and packed in reinforced, fumigation-free wooden boxes or honeycomb cardboard crates.

Shipping: Flexible global delivery terms (FOB, CIF, DDP) supporting sea freight, air cargo, and express courier services for urgent prototype needs.
