GRAPHITE

1. WHAT IS GRAPHITE

Natural flake graphite : is mined and processed from natural deposits.

It is low-density form of the element carbon.

Natural graphite is one of the crystalline forms of the element carbon. Its atoms are arranged in a hexagonal structure and form in a layered structure.

Natural graphite occurs in metamorphic rocks as well as in igneous rocks and meteorites. Under high pressures and temperatures, it converts to diamond.

2. PRODUCTION PROCESS OF GRAPHITE

After being mined, graphite ore is pre-processed through flotation technology to collect flotation graphite ore concentrate with a common carbon content of 85% to 95%.

3. PROPERTIES OF GRAPHITE

It has a high degree of crystallinity. It is the most commonly used form of graphite due to its unique properties, Graphite has a very high melting temperature (over 3,600 0C) with good thermal and electrical conductivity, lubricity, and resistance to corrosion and abrasion

Electrical conductivity
Thermal conductivity
Self-lubrication
High melting point
Corrosion resistance
Insoluble in water
Chemically inert

MAIN APPLICATION

it is used in many industrial applications including : Steel, Foundries, refractories, lubricants, batteries, automotive parts, carbon brushes, mettalurgy …

Refractory and Foundry materials: Natural flake graphite is often used in the production of refractory materials due to its ability to withstand high temperatures without melting or degrading

Refractory Materials

On account of its high-temperature stability and chemical inertness, graphite is the perfect candidate for refractory material. It is used in the production of refractory bricks as well as “Mag-carbon” refractory bricks (Mg-C). In addition, graphite is used to produce crucibles, ladles, and molds for holding molten metals. Moreover, graphite is one of the most basic materials used in the production of functional refractories for the continuous casting of steel.
In the production of iron, graphite blocks are used to produce a portion of the lining of the blast furnace. Their structural strength at high temperature, thermal shock resistance, high thermal conductivity, low thermal expansion, and good chemical resistance are highly important in this application.
The electrodes used in many electrical metallurgical furnaces are mass-produced from graphite, for instance, the electric arc furnaces used for processing steel.

Magical influence on foundry industry | Natural flake graphite

Lubricity is a property of a substance that describes its ability to reduce friction between two surfaces in contact. In the case of natural flake graphite, its flaky structure allows it to easily slide between surfaces, which makes it an excellent lubricant.

The foundry industry is one of the largest consumers of natural flake graphite. It is used as a mold release agent, a core component in foundry sand, and as a lubricant for machining parts. Its high lubricity and ability to withstand high temperatures make it an ideal material for foundry applications.
