NATURAL FLAKE GRAPHITE



Known for its high degree of macro-crystallinity, flake graphite’s high thermal and electrical conductivity and low spring-back properties make it excellent in molding, friction, and conductive applications. It is also a choice material for powder metallurgy, batteries, fuel cells, refractories, general lubricants, rubber compounds, pencils, gaskets, and polymer systems.

Pioneer Carbon India is pleased to offer a ready supply of commercial grade flake graphite in purity ranging from 80-97% carbon, and sizes from less than 1um to 800um.

PIONEER CARBON INDIA - Bulk Stocks are available in Chhattisgarh and Maharashtra- INDIA

NATURAL AMORPHOUS GRAPHITE:

Amorphous graphite, is a microcrystalline form of natural graphite used in drilling, friction, and a variety of lubricant products including greases and other forging lubricants. It excels in applications where low carbon content, and electrical and thermal conductivity is desired. Properly sized amorphous graphite powder is also used to create the correct balance between lubrication and mild abrasion in mechanical seal applications. Amorphous graphite provides exceptional value for engineered solutions requiring a lower cost graphite material.

Pioneer Carbon India is pleased to offer hundreds of grades of amorphous graphite, categorized by size and purity to fit your exact requirements. And with 120+ years of experience in grinding and sizing of these materials, our experts make it easy to identify and source the right graphite for your job.



PIONEER® NATURAL GRAPHITE SOLUTIONS REFRACTORIES:

Natural flake graphite has been extensively used in refractories to boost performance and service life. Natural graphite is still a vital component of modern refractory products and a prime choice for new developments. Refractories in steel ladles, basic oxygen furnaces (BOF), electric arc furnaces (EAF) and induction Furnace where Pioneer® Natural Graphite can contribute to smooth, economical and trouble-free operation.



PIONEER® NATURAL GRAPHITE PROPERTIES AND EFFECTS ON REFRACTORIES:

With its highly crystalline structure, Pioneer® natural flake graphite is a unique material, with unique properties. Additions of Pioneer® graphite to the refractory mix (a few percent up to 25%) can tremendously improve its service performance.

THERMAL SHOCK RESISTANCE:

Pioneer® Natural Graphite has a high thermal conductivity. When added to refractories, the internal thermal gradient between the hot and the cold face is considerably reduced, thus effectively decreasing internal stresses and improving thermal shock and spalling resistance.

CORROSION RESISTANCE:

Pioneer® Natural Graphite is not wetted by molten slag. When present in the refractory, Pioneer® Natural graphite prevents penetration of slag and molten metal through the crack network inside the refractory. That effectively improves corrosion resistance.

OXIDATION RESISTANCE:

Research work indicates that 2 factors directly affect the oxidation resistance: particle size and purity. It has been determined that oxidation takes place only on the edges of the graphite flakes or where impurities or inclusions can be found. Larger and purer flakes are therefore more resistant. With larger flake size, higher thickness and higher purity, Pioneer® Natural Graphite shows excellent resistance to oxidation, and this translates into longer refractory life.



ADDITIONAL PROPERTIES AND ADDED BENEFITS PIONEER NATURAL® GRAPHITE:

  • Outstanding resistance to chemical attacks.
  • Stability over a wide range of temperature with very low thermal expansion coefficient.
  • Reduced tool wear during pressing because of its unique lubricant action.
  • Malleable and very easy to model into shape.
Pioneer® Natural Flake Graphite is sold in a wide range of products distinguished by particle size distribution, chemistry and carbon content. Pioneer Carbon mines the graphite from its own source in Tanzania, African Country. We guarantee very fast and reliable deliveries. Our natural graphite is thoroughly controlled in our laboratories to ensure quality, consistency and above all, total customer satisfaction.
