Low-ash, low-volatile, high-BTU hard coal mineral engineered for filler, casting, and industrial applications.

Anthracite Coal, also known as Hard Coal, is a naturally occurring, low-ash, low-volatile, homogeneous coal with a high BTU value. Due to its carbon content, stability, and clean-burning characteristics, anthracite is widely used in products and processes requiring a low-conductive, cost-effective black mineral filler and carbon additive.

Anthracite Coal (Hard Coal)

Anthracite coal represents the highest rank of naturally occurring coal, formed through extensive geological carbonization. Its structure is dense and stable, with minimal volatile content compared to other coal types.

Because of its low ash and low volatile matter, anthracite provides consistent carbon performance in industrial systems. It is frequently selected where a reliable, economical carbon source is required without high electrical conductivity. Typical product specifications include:

  • Carbon Content: 85% typical
  • Particle Size: 2” – 10 μm

Applications

Anthracite Coal Applications

Anthracite is used in applications requiring stable carbon addition, black pigmentation, and mineral filler performance.

Casting

Used as a carbon additive and filler in metal casting processes.

Coatings

Provides black pigmentation and filler performance in specialty formulations.

Cored Wire

Used as a carbon source in metallurgical wire products.

Friction Products

Used in brake linings and friction systems for durability and wear resistance.

Plastics & Polymers

Serves as a low-cost black mineral filler in polymer formulations.

Rubber Goods

Enhances reinforcement and pigmentation in rubber compounds.

How It Works

Material Characteristics

Anthracite coal does not soften or flow during heating and maintains structural integrity under high-temperature conditions. Its high BTU value makes it an efficient energy source, while its low ash and low volatile content make it suitable for clean, controlled carbon applications.

Particle Size Flexibility

Available in a wide particle size range, from coarse granules to finely milled powders, anthracite can be tailored to meet specific injection, blending, or filler requirements.
