Graphene vs. Diamond

The debate between Graphene and diamond has been going on for as long as chemistry textbooks have existed. Diamonds are a tough substance, but they can also be costly due to their rarity. Graphene is composed of carbon atoms that have been layered one atom thick, and it can absorb blows as powerful as a punch through steel. Even though diamonds are tough, they can scratch other materials, making them an excellent material for electrochemical applications such as batteries.

Graphene and diamond have several significant differences, one of which is that Graphene can be sandwiched between two biomolecules. Graphene can be used to sandwich molecules in a watery environment and may even improve the performance of chemical sensors in the future. Carbon nanotube chemical sensors are constructed from an insulating base that has been coated with Graphene. They can detect low concentrations of gases such as hydrogen or oxygen, among other things. As a result, Graphene is considered to be the ultimate material.

What is Graphene?

Each atom in a graphene sheet has three -bonds and contributes one electron to a conduction band that spans the sheet. This bonding is found in carbon nanotubes, polycyclic aromatic hydrocarbons, fullerenes, and glassy carbon. Theories best describe its unusual electronic properties for massless relativistic particles. Charge carriers in Graphene have a linear rather than quadratic dependence on momentum, and bipolar field-effect transistors can be made with Graphene.

The material has large quantum oscillations and nonlinear diamagnetism. Graphene conducts heat and electricity very well. Graphite is black because it absorbs all visible light wavelengths, but a single graphene sheet is nearly transparent due to its extreme thinness. It is also 100 times stronger than steel of the same thickness. The transmitted light image of a suspended graphene membrane. This one-atom-thick material absorbs about 2.3 percent of light and is visible to the naked eye.

Graphene has been theorized for decades, and it has probably been produced in small quantities unknowingly for centuries by using pencils and other graphite-based products. It was first seen in an electron microscope in 1962, but only on metal surfaces.

Andre Geim and Konstantin Novoselov found, isolated, and studied the material in 2004 at the University of Manchester. In 2010, Geim and Novoselov won the Physics Nobel Prize for their “groundbreaking experiments on the two-dimensional material graphene.” Isolating high-quality Graphene was surprisingly simple.

Graphene is a valuable nanomaterial because of its high tensile strength, electrical conductivity, and transparency and is the world’s thinnest two-dimensional material.

In 2012, the global graphene market was worth $9 million, driven by research and development in semiconductors, electronics, batteries, and composites.

What is a Diamond?

Diamond is a solid form of carbon with atoms arranged in a diamond cubic crystal structure. Graphite is the most chemically stable form of carbon at room temperature and pressure, but diamond converts to it very slowly. Diamond is the most complex and thermally conductive natural material, ideal for industrial applications like cutting and polishing tools. They also allow diamond anvil cells to subject materials to extreme pressures.

Because diamond’s atomic structure is rigid, few impurities can contaminate it (two exceptions are boron and nitrogen). Destruction or impurities (one per million lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple (radiation exposure), pink (radiation exposure), orange (radiation Diamond has a high refractive index and optical dispersion.

Most natural diamonds are 1 billion to 3.5 billion years old. Most formed between 150 and 250 km (93-155 mi) deep in the Earth’s mantle, but some reached 800 km (500 mi) (500 mi). Carbon-containing fluids dissolved minerals and replaced them with diamonds. They were brought to the surface by volcanic eruptions and deposited in igneous rocks called kimberlites and lamproites.

Cryogenic vapor deposition of synthetic diamonds from high-purity carbon or hydrocarbon gases (CVD). Imitated diamonds can also be made of zirconia and silicon carbide. Optical or thermal conductivity tests usually identify natural, synthetic, and imitation diamonds.

What Makes Graphene so much Stronger than a Diamond?

Graphene is significantly stronger than diamond because it is a single sheet of carbon layers rather than a series of layers like a diamond.

Nanotubes are formed when the atoms within these carbon layers bind together to form a tube. Nanotubes are hollow tubes with a diameter of only one nanometer and smooth sheets of carbon atoms curled around the tubes made of carbon.

Because of the strong bonding nanotubes, Graphene is the most rigid substance ever discovered.

It is also important to note that the hardness of Graphene and diamonds is significantly different due to the differences in their tensile strength, melting and boiling points, and young modulus.

Here is a description of each factor and the reasons for each factor.

Is Graphene the Same as a Diamond?

All three of these materials are composed of the same element – carbon – but how the carbon atoms are arranged and bonded together makes them distinct from one another. Graphene is a sheet of carbon that is only one atom thick and has solid horizontal bonds between the atoms that run through it.

Is there Anything that is More Durable than a Diamond?

Diamond is currently considered the world’s hardest known material, surpassing all other known materials. However, scientists have calculated that a material known as quartzite boron nitride (w-BN) has a greater indentation strength than diamond when considerable compressive pressures are applied under indenters.

What is the Most Powerful Substance on the Face of the Planet?

In all of its natural forms, diamond is the hardest substance on the planet, and it is an allotrope of carbon, making it the most complex substance known to man. Diamond has the highest level of Mohs hardness – grade 10 – of any mineral. It has a microhardness of 10000kg/mm2, 1,000 times higher than quartz and 150 times higher than corundum, making it the hardest substance known.

Is it Possible for a Bullet to Shatter a Diamond?

Because diamonds are complex but not challenging, they are suitable for jewelry. That means that even though they can cut through rock like butter when used in drill bits if you hammer that same drill bit, the diamond portion of the drill bit will shatter at certain angles due to its fracture.

Why is Graphene Superior to Diamond in Terms of Strength?

This is because the carbon layers within a graphite stick are very easily removed. However, because the atoms within those layers are extremely tightly bonded, Graphene, like carbon nanotubes (but unlike graphite), is extremely strong, possibly even more potent than diamond.


Graphene is 300 times stronger than steel and has a more rigid surface than diamond. It’s also very flexible and a good conductor of electricity and heat. It may even replace silicon and other conventional materials shortly, making airplanes lighter and more robust. . It could also replace chemical batteries and superconductors with Graphene. If the research continues, it May transforms the technology industry. Scientists are still trying to figure out how Graphene works for the time being. In the Graphene vs. diamond debate, the next big question is whether Graphene is more durable than diamond. Diamond is a non-cloudy, highly durable material, whereas Graphene is much more complicated. Graphene has a tensile strength that is significantly higher than diamond. One of the most critical debates in nanomaterials will be Graphene vs. diamond.
