What is the most difficult chemical in the World?


When we think of the most durable substance on earth most of us tend to concentrate on diamond. But, the answer to this question isn't easy as you might think. It is also important to think about carbon nanotubes as well as boron nitride. While they appear like diamonds, their structures are significantly different. These substances are much more hard than diamond and are more stable chemically in extreme temperatures.


Diamond


Due to the unique molecular structure of diamond, diamond is one of the strongest materials that exists. The covalent bond that links carbon atoms in diamond traverses space makes it the most durable substance on the planet. This bond is extremely solid and stops any free electrons from leaving the diamond. Because diamond is very hard and strong, it is commonly used as a tool to sharpen hard edges.


Although diamond is the strongest material on the planet, other substances have also been identified which are more durable than diamond. Cubic boron Nitride is the second-hardest material, with the Vickers hardness of about 50 GPa. Though initially thought to be harder than diamonds, this claim was based on only theoretical simulations. It is extremely rare and isn't easily discovered in the natural world.


If a substance is exposed to extreme pressure and heat it will become more difficult. Diamond is the strongest material there is no other object that has endured this extreme pressure and heat. The beauty of diamond is incredible, and many feel that no other material can rival it.


Carbon nanotubes


Carbon nanotubes are made of carbon atoms and tightly packed into a small space. The length of a Nanotube is described by a length graph, W, and the angle a between the directions u and w is a factor of 60 degrees in the direction of clockwise.


Carbon nanotubes show the properties of semiconductor and metallic. Their electrical conductivity ranges from 0 to 2 electronvolts. Spectroscopy allows you to identify the material's structure and non-tubular carbon. This technique is able to determine the structure and quality of carbon nanotubes that are produced.


Carbon nanotubes are extremely durable. Their tensile force is similar to that of steel, which is one of the most durable materials. In fact, researchers have been able to stretch individual carbon nanotubes to over 14 percent of their original length, which is far higher than previous research. This research has established an upper limit on carbon nanotubes' strength.tongruncms
