Carbon, from Diamond to Yarn

s15sOur team really loves innovation, specially if it increases human life. Our firm is a yarn producer as you know, and carbon is one of the elements the compose our fibers. Are you ready to discover which are its own properties?

Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. It is present in all forms of carbon-based life, and in the human body carbon is the second most abundant element by mass (about 18.5%) after oxygen.[16] This abundance, together with the unique diversity of organic compounds and their unusual polymer-forming ability at the temperatures commonly encountered onEarth, make this element the chemical basis of all known life.

The atoms of carbon can be bonded together in different ways: allotropes of carbon. The best known are graphite,diamond, and amorphous carbon.[17] The physical properties of carbon vary widely with the allotropic form. For example, graphite is opaque and black, while diamond is highly transparent. Graphite is soft enough to form a streak on paper (hence its name, from the Greek word “γράφω” which means “to write”), while diamond is the hardest naturally-occurring material known. Graphite is a very good conductor, while diamond has a very low electrical conductivity. Under normal conditions, diamond, carbon nanotubes, and graphene have the highest thermal conductivities of all known materials. All carbon allotropes are solids under normal conditions, with graphite being the most thermodynamically stable form. They are chemically resistant and require high temperature to react even with oxygen.
