C onvert coal into Nano graphite Powder A team of international researchers has proven that it only takes 15 minutes to transform pulverized coke into high-value coal 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, 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 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 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 transforms pulverized coke. This process also involves copper foil, hydrogen and polycrystalline graphite. The team, including researchers from New York (also included), Nepal, and China, believe that this new coal-to-graphite conversion method can also be improved and implemented at a larger scale to produce higher quantities and quality of graphite.

What? It is a good idea to use a bilingual translator Graphite
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 extremely brittle, breaks with a light touch, and has an extremely low specific gravity. It is a material that is resistant to heat, and almost inert if it comes into contact with any other substance. 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 the 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 exposed to heat and pressure during regional metamorphism. This results in marble, schist, or gneiss containing tiny flakes and crystals of graphite.
If the concentration of graphite 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 product produced is referred to as “flake-graphite.”
Some graphite can be formed from metamorphism. Carbon, oxygen and hydrogen are the major components of coal’s organic material. The heat generated by metamorphism degrades organic coal molecules, releasing hydrogen, oxygen, nitrogen and sulfur. What is left after metamorphism is almost pure carbon that crystallizes to form 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. 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.
Carbon atoms form a hexagonal graphite network that is one atom thick. The sheets are not well connected, and can easily be cleaved or slide over each other when a slight force is applied. This gives graphite a very low level of hardness, a perfect cleavage and slickness.
Carbon atoms of diamonds, however, are linked in a frameworks-like 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 a hard material.
