Graphite fines (GPC/CPC)

Graphite Fines (Calcined Petroleum Coke and Graphitized Petroleum Coke)

Calcined Petroleum Coke (CPC)
Calcined Petroleum Coke (CPC) is a carbon-rich solid material produced n a rotary kiln or vertical shaft furnace at high temperatures (around 1200–1350°C) to remove volatile matter and moisture. This process improves its physical and chemical properties.
Applications of CPC
  • Aluminum Industry – As a primary carbon source in anodes for aluminum smelting (Hall-Héroult process).
  • Steel Industry – As a carbon additive in steel and foundries.
  • Titanium Dioxide Production – As a reducing agent in chlorination processes.
  • Graphite Electrode Manufacturing – Feedstock for graphite electrodes used in electric arc furnaces (EAF).
  • Other Uses – In carbon pastes, carburizers, and specialty carbon products.
Chemical Specification of Calcined Pet Coke
Property Typical Range
Fixed Carbon 97–99.5%
Sulfur Content 0.5–4% (low-sulfur grades <1%)
Volatile Matter < 0.5%
Ash Content < 0.5%
Real Density 2.03–2.1 g/cm³
Electrical Conductivity High

Graphitized Petroleum Coke (GPC)

Graphitized Petroleum Coke is a high-purity carbon material made by graphitizing of petroleum coke at very high temperatures (typically 2500–3000°C) in an electric resistance furnace. This process rearranges the carbon atoms into a graphitic crystalline structure, improving its conductivity and purity.
Applications of GPC
  • Steel and Foundry Industry – As a recarburizer or carbon raiser in ladle metallurgy.
  • Graphite Electrode Production – Raw material for UHP electrodes.
  • Battery Industry – In anode materials for lithium-ion batteries.
  • Other Uses – Speciality carbon products like graphite crucibles, brushes, etc.
Chemical Specification of Graphitized Petroleum Coke
Parameter Typical Range
Fixed Carbon 99%–99.9%
Sulfur Content 0.01–0.03% (ultra-low sulfur)
Ash < 0.2%
Moisture < 0.5%
Real Density 2.10–2.20 g/cm³
Electrical Conductivity Very High
Crystal Structure Graphitic
