onvert coal into Nano graphite
Powder
A team of international researchers has proven that it only requires 15 minutes for pulverized coke to be converted into high-value coal
Nano graphite
. Researchers explain in the Journal Nano-Structures & Nano-Objects that microwave ovens are used to create an atmosphere where raw coal can be successfully transformed into Nano graphite. Nano graphite has many uses, including as a lubricant for fire extinguishers and lithium-ion batteries.
They believe that this “metal assisted microwave processing one step method” is a relatively simple and inexpensive method to convert coal in Wyoming’s Powder River Basin. According to TeYu Chen’s team at the University of Wyoming despite previous studies showing that microwaves could reduce coal moisture and remove sulfur as well as other minerals but most of these methods required special chemical pretreatment of the raw coal. The experiment only required the pulverization of the coal. After that, put the coal powder on copper foil. Seal it in glass containers with a mix of hydrogen and an argon mixture. Finally, put it in the microwave.
Chris Masi is the lead author. He stated that “by cutting the copper into a fork form, microwave radiation can generate sparks. These sparks can create extremely high temperatures of over 1,800 degrees Fahrenheit in just a few second.” The high temperature then transforms pulverized coke. This process also involves copper foil, hydrogen and polycrystalline graphite. The team (which includes researchers from New York Nepal and China) believes this new coal-to-graphite conversion method can improve and be implemented at a large scale in order to produce graphite materials of higher quality.

Graphite This is a natural form of crystalline Carbon. It is a mineral element found in metamorphic or igneous rocks. Graphite can be described as a mineral that is characterized by extremes. It is soft and cleaves easily with very little pressure. It also has a low Specific Gravity. It is extremely heat resistant and virtually inert with most other materials. This extreme property gives it a variety of uses in manufacturing and metallurgy.
Graphite, a mineral, is formed when carbon is heated and pressed in Earth’s crust or upper mantle. To produce graphite, temperatures and pressures between 750°C and 75,000 lbs per square inch are needed. These correspond to granulite facies.
The vast majority of the graphite found on Earth’s surface was created at the convergent plates boundaries when organic-rich limestones and shales were subjected under the pressure and heat of regional metamorphism. This results in marble, schist, or gneiss containing tiny flakes and crystals of graphite.
If the concentrations of graphite are high enough, the rocks can be mined. They can then be crushed into flakes and separated by specific gravity or flotation. The product produced is called “flake-graphite.”
Some graphite is formed by metamorphism. The organic material of coal is primarily composed of carbon, hydrogen, oxygen and sulfur. The heat generated by metamorphism destroys coal’s organic molecules, releasing hydrogen, oxygen, nitrogen and sulfur. What remains is almost pure carbon that crystallizes to mineral graphite.
This graphite appears in “seams” which correspond with the original coal. This material is mined as “amorphous Graphite.” This is not the correct use of “amorphous”, as it has a crystal structure. The material is similar in appearance to coal lumps, without the banding.
Diamonds and Graphite
Graphite Diamond and carbon are two minerals that contain carbon. Diamond is formed in the mantle by extreme heat and pressure. The majority of graphite that is found on Earth’s surfaces was formed at lower temperatures and under less pressure in the crust. Graphite has the same chemical composition as diamond but is structurally very different.
The graphite sheets are formed by a hexagonal web of carbon atoms. Each sheet is one atom thick. The sheets are not well connected, and can easily be cleaved or slid over each other when a slight force is applied. This is what gives graphite it’s very low hardness. It also gives it its perfect cleavage and its slick feel.
Carbon atoms of diamonds are linked in a frameworks-like structure. Every carbon atom in a diamond is connected to four other carbons by strong covalent bonds. The arrangement of the atoms keeps them firmly in position and makes diamond a hard material.
