onvert coal into Nano graphite
Powder
A team of international researchers has proven that pulverized coke can be converted into high-value coal in just 15 minutes.
Nano graphite
. Researchers explain in their research, published in the journal Nano-Structures & Nano-Objects that microwave ovens are used to create a conducive environment for raw coal to be converted 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 this coal. The experiment only required the raw coal of the Powder River Basin to be pulverized. 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 foil in a fork-shaped shape, microwaves will generate sparks. These can create extremely high temperatures of over 1,800 degrees Fahrenheit innerhalb of a few second.” The high temperature, then, transforms the coal. 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 higher quality graphite materials.

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 very hard, but cleaves easily with a light touch. It also has a very small specific gravity. It is resistant to heat, and almost inert if it comes into contact with any other material. 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 upper and crust mantle. To produce graphite, temperatures and pressures between 750°C and 75,000 lbs per square inch are needed. These correspond to the metamorphic facies granulite.
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 exposed to heat and pressure during regional metamorphism. This results in marble, schist, or gneiss containing tiny crystals of graphite.
If the graphite concentration is high, the rocks can be crushed into flakes and then processed using specific gravity separation (or froth floatation) to remove the lower density graphite. The resultant product is known as “flake-graphite.”
Some graphite is formed by metamorphism. The organic material of coal is primarily composed of carbon, hydrogen, oxygen and nitrogen. 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 layer coal. This material is mined as “amorphous Graphite.” This is not the correct use of “amorphous,” as it has a crystalline composition. 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. Under extreme heat and pressurized, diamond is formed in the mantle. Most of the 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 the reason graphite has a very low level of hardness. It also gives it its perfect cleavage and its slick feel.
Carbon atoms of diamonds, however, are linked in a framework structure. Each carbon atom has strong covalent bonds that link it to four other carbons in a three-dimensional web. The arrangement of the atoms keeps them firmly in position and makes diamond a hard material.
