What is fatty graphite?
Fatty graphite is a type of inorganic carbon powder and one of the natural forms of carbon that crystallizes hexagonally. Due to its rarity (even less than coal powder), this material is considered a strategic material in the world. Preservation of crystalline properties, ability to pass electricity and high tolerance of thermal shocks have caused this strategic material to be used in the production of pencils, electrode pigment, coating of sands in the form of solvent in casting, steel industries, etc.
Fatty graphite is mainly used in the foundry industry and is often used for color coatings and is produced by grinding and granulating graphite. The production of graphite is technical due to the properties of static electricity. This substance is found in metamorphic and igneous rocks and is usually formed when carbon in the earth’s crust is subjected to high pressure and temperature. The appearance of this mineral has a black or gray color and it is very soft, so you can recognize it in this way: with a little pressure between two fingers, it completely covers the contact surface of the skin and makes it shiny, and you can feel the oiliness on the skin. will be
Applications of fatty graphite
Fatty (natural) graphite powders are used for carbonization of raw materials to make different alloys and also for use in induction furnaces and other industries. The main use of this product is in the industry of pads, clutch plate and lubrication, and fatty graphite is also used as a raw material for steel in the following cases:
Production of steel products
Production of refractory products used in the metallurgical industry
Used as a lubricant in forging and extrusion industries
Used in resin production industries
Casting industries
Dry drilling industry
Refractory industries
Paint industries
Nuclear reactors
power industy
Properties of fatty graphite
Fatty graphite has a black color and a very light weight. This product is soft and highly refractory and also has excellent thermal stability. It is chemically neutral and its friction coefficient is low. It has the highest electrical conductivity among non-metals and its thermal conductivity is comparable to copper and silver. Its thermal expansion is low. Fatty graphite has a crystalline structure and is produced in the range of 80 to 98% graphite carbon, as its name suggests. Sheet graphite has a completely sheet morphology and natural graphite is considered a mineral with a high degree of transformation.
