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 how to successfully convert raw coal into Nano-graphite using microwave ovens in a study published in Nano-Structures & Nano-Objects. Nano graphite has many uses, from lubricants to lithium-ion batteries and fire extinguishers.
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 coal to be pulverized. After that, put the coal powder on copper foil. Seal it in glass containers with a mix of argon hydrogen gas. 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. Contrastingly, it is highly resistant to heat. 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.
Most 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 crystals of graphite.
If the concentrations of graphite are high enough, the rocks can be mined. They are then crushed into a size that releases the graphite flakes, and the low-density material is removed using specific gravity separation (SGS) or froth floatation. The product is called flake graphite.
Graphite can be formed from coal seams that have undergone metamorphism. Carbon, hydrogen, oxygen and sulfur are the major components of coal’s organic material. 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 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. 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. The graphite is characterized by its low hardness. It also has a perfect cleavage and a slippery 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 network. The arrangement of the atoms keeps them firmly in position and makes diamond an extremely hard material.
