A high density graphite block is a solid piece of engineered graphite designed for industrial applications requiring superior strength, thermal stability, and conductivity. Produced from high-purity petroleum coke and processed through advanced baking and graphitization techniques, these blocks are known for their excellent density, mechanical strength, and resistance to high temperatures and chemicals.

They are widely used in metallurgy, mold making, furnace construction, EDM (electrical discharge machining), aerospace, and semiconductor industries.

Key Features:

• High Bulk Density: Typically ranges from 1.75 to 1.91 g/cm³, providing excellent strength and durability.

• Superior Heat Resistance: Withstands continuous use at temperatures up to 3000°C in inert atmospheres.

• Excellent Electrical and Thermal Conductivity: Ideal for electrochemical and heating applications.

• Low Porosity & Fine Grain Structure: Ensures stability, precision, and resistance to oxidation or gas penetration.

• Machinability: Can be easily cut, shaped, and finished into complex components and molds.

Typical Applications:

• Metallurgical Industry: Used as lining material, crucibles, or support components in high-temperature furnaces.

• EDM (Electrical Discharge Machining): As electrodes for precision metal forming and mold making.

• Semiconductor & Solar: Carrier plates, heating elements, and sintering trays.

• Glass & Ceramics: Molds for casting or sintering high-temperature materials.

• Chemical Industry: As reaction vessels, anode/cathode blocks, and corrosion-resistant parts.
