(What is ​amorphous graphite powder?)

Amorphous graphite, earthy graphite, microcrystalline graphite and black lead powder. Amorphous graphite does not really have no graphite crystals as its name suggests, but its crystals are too small and have a microcrystalline structure. X-ray analysis shows that amorphous earthy graphite contains 15% to 45% of crystalline graphite, so amorphous graphite is also called microcrystalline graphite.

Amorphous earthy graphite can be divided into two types according to its output form: dispersed earthy graphite ore and dense massive earthy graphite ore.

Dispersed earthy graphite ore mainly occurs in the broken zone or cleavage fissure surface of flake graphite ore, and has a mylonitic structure. The composition is complex and unstable, mainly composed of plagioclase, quartz, grafît, tremolite, chlorite, etc. The scales are crushed and broken into small fragments, some of which are in the shape of black stars, and their crystal shapes are difficult to identify with the naked eye. The ore grade is low, generally 2%~3%, and has no industrial value

What are the main characteristics of earthy graphite?

Dense massive earthy graphite ore is mostly formed by contact metamorphism of thermal metamorphism in coal fields. The ore is a black dense block with a range of characteristics from graphite transition to anthracite. The graphite content varies, generally 60%~80%, the minimum is 15%, and the maximum is more than 90%. In addition to graphite, the constituent minerals include sericite, quartz, pyrite, calcite, limonite, clay, etc. This is the main characteristic of earthy graphite.

What is the distinguish betweene arthy graphite and flake graphite?

Graphite crystals are scaly; this is metamorphosed under high-intensity pressure, and there are large and fine scales. This kind of graphite ore is characterized by low grade, generally between 2-3%, or 100-25%. It is one of the most floatable ores in nature, and high-grade graphite concentrate can be obtained through multiple grinding and selection. The floatability, lubricity and plasticity of this type of graphite are superior to other types of graphite; therefore, it has great industrial value.

earthy graphite

Also known as amorphous graphite or hidden quality graphite, the crystal diameter of this graphite is generally less than 1 micron, it is an aggregate of microcrystalline graphite, and the crystal form can only be seen under an electron microscope. This type of graphite is characterized by an earthy surface, lack of luster, and poor lubricity. Higher grade. General 60 to 80%. A few are as high as 90% or more. Ore selectivity is poor.
