Amorphous Graphite is a form of natural graphite with poorly educated and the crystal structure is also called kryptokrystalicznym graphite or black. Just as coal is the result of metamorphic rocks rich in organic carbon. The main characteristics of amorphous graphite are good thermal and electrical conductivity, low coefficient of thermal expansion, high chemical and thermal resistance, excellent lubricating properties. However, in contrast to the graphite flake, does not exhibit anisotropy of these properties.

Types and parameters On the basis of grain size and carbon content is classified a number of species with different characteristics and purpose. In the process of treatment, grinding and separation of amorphous graphite is replaced by a number of its form, it is a powder with an average grain size of less than 45 to 75 meters below me a coarse powder of 150? M, the grains of grain size in ranges from 0.1 mm to 9 mm and a graphite Lump and briquetted sizes ranging from 20 mm to 100 mm.The carbon content of amorphous graphite ranges from 70% to 90%. Other important characteristics of amorphous graphite, are: the content of volatile matter and sulfur compounds and moisture, which should not exceed 2% especially in metallurgical applications.

Main applications:

1. Casting In 1980-1945 amorphous graphite is used for making powders, and czernideł posypek the foundry. It can be used both in powder form and as a suspension based on water or other liquids. Owing to the low content of harmful elements such as sulfur, phosphorus, nitrogen does not affect the phase of damaging the surface of castings. This is an excellent, cost-effective separator of pattern making and molding, where he also serves as a cover of refractory and protects against damage to both form and cast against the formation of defects in the type of burns, penetration, and crusts.
2. Iron carburization For the Carburizing of iron in electric arc furnaces and induction in the mirror and solid feedstock, is designed in the form of graphite grains Z85. However, for blowing air feeder apply more granular graphite-W80-X. For the Carburizing in cupola is designed for coarse fraction gafit N80, is resistant to oxidation and can increase the carbon content at low cost. Very good solubility of graphite in cast iron, low in phosphorus, nitrogen, hydrogen and sulfur, and modifying the properties of graphite have a positive influence on the crystallization process of iron, the result raises the mechanical performance and utility castings.
3. Metallurgy Rolling of steel, particularly for tube mill and blacksmith shop is designed graphite-W80-45 and W90-45. It is a dry heat-resistant separator and grease, do not emit harmful substance is not harmful to health and the environment, not a destructive influence on metal surfaces results in lower consumption of machines and raises the efficiency of production.
4. Other applications In addition, amorphous graphite is used as a feedstock for production of refractory materials, additives for the production of insulating materials and sealants. In the form of powder, amorphous graphite is used for the manufacture of brake linings and friction, antistatic and anti-adhesive coatings, and various layers of protection. Transport and storage Amorphous graphite is packaged in 25 kg bags, delivery takes place in a large polypropylene bags per pallet BigBags of 1000 kg. However, coarse fractions, packaged in bulk BigBags-i. Packages are designed for mechanical handling and storage facilities at the same time protect and equipment from dust, graphite dust troublesome. The storage must be in a dry and ventilated, protected from access by the fire. Packages have a clear indication as to the type of material and batch number, this is the basis for determining the composition, nature and destination of the goods prior to its use.
