It is of vital importance to life on Earth, allowing carbon to be continually reused and recycled. More readily available historically was soot or charcoal. One of the most amazing properties of carbon is its ability to make long carbon chains and rings. Where more than one isotope exists, the value given is the abundance weighted average. It is flammable. Next week we're heading to the top of group one to hear the story of the metal that revolutionised the treatment of manic depression. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). ADVERTISEMENTS: Steel has got a variety of applications for engineering purposes due to the wide range of physical properties obtainable by changes in carbon content and heat treatment. Carbon fibre is a strong and reliable fibre consists of carbon material. That is why diamonds are always cold to the touch. The man responded so well that within days he was transferred to a normal hospital ward and was soon back at work. It is the hardest material known to man and more or less inert - able to withstand the strongest and most corrosive of acids. You can find it available as coal, graphite in the elemental state.

The higher carbon content, the higher steel strength and the lower its ductility. Carbon comes in many different forms (so-called allotropes), from the graphite found in pencils to the world's most expensive diamonds. Mass-produced automobiles are not yet adopting carbon fiber; this is because of the increased raw material cost and necessary changes in tooling, still, outweighs the benefits. Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion.
