Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...

The process that turns coal into diamonds is called carbonization. It involves heating the coal to extremely high temperatures in the absence of oxygen. This process causes the carbon in the coal to break down and form a diamond. It is unlikely that diamonds are made of coal metamorphism. Coal, which is the primary source of energy on Earth, is ...

Are Diamonds Made From Coal? Contrary to what you might have learned in science class, diamonds are not made from coal. The old wives' tale that diamonds were once pieces of coal that have evolved after years under high pressure and temperature is nothing more than a common myth.

Start with Carbon . Understanding the chemistry of a diamond requires a basic knowledge of the element neutral carbon atom has six protons and six neutrons in its nucleus, balanced by six electrons. The electron shell configuration of carbon is 1s 2 2s 2 2p has a valence of four since four electrons can be accepted to fill the 2p orbital.

The Scientific Process of Diamond Formation. Diamonds were founded in the 19th century in South Africa. They are formed deep within the Earth in an area called the mantle. Here, intense pressure changes the molecular structure of carbon by crushing its atoms and forcing them into a whole new latticelike structure.

The process of making diamonds from coal is called carbonadoing, and it is a very difficult and expensive process. The first step is to find a deposit of coal that is at least % pure carbon. The next step is to heat the coal in an environment that has no oxygen, such as in a vacuum or in an inert gas. The coal is heated to a temperature of ...

However, it is rare for coal to be the main factor in diamond formation. In fact, most diamonds are millions of years old. In addition, diamonds are formed in impact sites where coal was deposited. But the process is different if coal is present in an impact site. Diamond formation is a complex process requiring high temperatures and pressures.

A skilled diamond cutter may choose to shatter a diamond, but he or she only creates more diamonds. In contrast, coal dust dirties and blackens everything. When inhaled, it stays in the lungs forever. Longterm exposure causes black lung disease in coal miners. Sometimes strong winds will turn coal dust into an airborne irritant.

The majority of labgrown diamonds are created using a process called highpressure, hightemperature (HPHT) synthesis. In this method, diamond seeds are placed in a chamber with carbonrich material and then subjected to extreme pressure and heat. Over time, the seeds grow into fullsized diamonds. HPHT synthesis is the most common method for ...

The cooling takes place when the diamonds are forced to the surface by the volcanic eruption. Coal is Formed Mostly From Plant Material Like diamonds, coal was formed billions of years ago. However, unlike diamonds, coal's carbon comes from many different substances, most notably, from decomposed plants.

In the creation of a diamond, there was never coal involved. In fact, most dated diamonds are substantially older than Earth's first land plants, which are used as a product when coal is formed. Diamonds deteriorate to graphite under normal settings because graphite has a lower energy configuration.

A key part of the process is the speed: it has to happen quickly, blasted to the surface. If you slowly traverse the distance, then you also slowly pass from the diamond part of the phase diagram to the graphite portion, and there's plenty of time for the diamonds to simply alter to graphite in the lower pressure/temperature conditions.

The most direct way to turn coal into diamond is through a process called chemical vapor deposition (CVD). In a CVD reactor, a mixture of gasses is passed over a substrate material, and the gasses deposit a thin film of carbon onto the substrate. If the conditions are right, the carbon film will crystallize into diamond.

Because of the tremendous pressure that exists in this area of the earth and the extremely high temperatures, a diamond begins to develop gradually over time. The entire process takes between 1 billion and billion years, which corresponds to around 25 percent to 75 percent of the age of our planet's crust.

The process of metamorphosis involves compressing a solid material and heating it. When coal is compressed, it undergoes a chemical transformation that changes the carbon content. In some cases, this transformation can take hundreds of years. During this transformation, the carbon content of the coal decreases, thereby changing it into diamond.
