Calcined Anthracite Coal is produced by heating high-grade anthracite to elevated temperatures to increase carbon content, improve conductivity, and reduce moisture and volatile matter. Available as Gas Calcined Anthracite (GCA), this upgraded carbon material is widely used in electrode manufacturing, smelting operations, and advanced carbon applications requiring purity and consistency.
Calcined anthracite is manufactured by heating anthracite coal to temperatures as high as 2000°C, depending on the calcination method. This high-temperature treatment drives off moisture, volatile components, improving the homogeneity and structural ordering of anthracite coal. By reducing volatile components and stabilizing the carbon matrix, calcined anthracite delivers improved consistency in metallurgical and electrode manufacturing processes.
Compared to un-calcined anthracite, calcined anthracite offers higher carbon content, improved thermal conductivity, increased electrical conductivity, and greater chemical and structural stability.
Typical specifications include:
Propriétés
Calcined Anthracite Coal provides enhanced carbon performance for metallurgical and electrode applications.
Applications
Calcined anthracite is used in applications requiring conductive carbon, structural integrity, and metallurgical consistency.
Used in friction products as a durable carbon-based additive to balance friction stability, wear control, heat resistance, and noise performance.
Supports carbon control and thermal stability in industrial furnace systems. Used in tamping paste formulations requiring stable carbon content and consistent conductivity.
Acts as a high-purity carbon source in smelting and metallurgical operations and provides structural carbon for high-temperature industrial components.
Fonctionnement
Gas Calcined Anthracite is produced in gas-fired furnaces at temperatures lower than those used in electrical calcination. Because of the lower calcination temperature, GCA is:
