Carbon Nanotube Applications and Uses. The properties of carbon nanotubes have caused researchers and companies to consider using them in several fields. The following survey of carbon nanotube applications introduces many of these uses.
They are brittle. Insoluble in water but soluble in non-polar solvents such as tetrachloromethane and petrol. Do not conduct electricity. Molecules do not carry a charge so even when melted, molecular solids cannot conduct. Giant molecular solids Diamond and graphite /**/ Diamond: Is made up of a lattice of carbon atoms.
Does graphite conduct electricity? Explain. Graphite is made up of layers of carbon atoms, and there are weak forces between these layers, allowing charged electrons to move freely between the layers> Therefore even though graphite is a giant molecular covalent substance it is a conductor.
Why does GRAPHITE conduct electricity and heat? In graphite, one non-bonding electron from each carbon atom is delocalised and these mobile, delocalised electrons travel between layers through the structure and allow graphite to conduct thermal energy / carry charge and allow a current to flow.
Because of its ability to conduct electricity and withstand heat, graphite is used in making electrodes, as lubricant for machines, and in nuclear reactors to absorb neutrons. Graphite is used as lubricant in machines, which have to be operated at high temperatures, because oil or grease vaporizes immediately at high temperatures.
Note: The logic of this is that a piece of graphite ought only to conduct electricity in 2-dimensions because electrons can only move around in the sheets - and not from one sheet to its neighbours. In practice, a real piece of graphite isn't a perfect crystal, but a host of small crystals stuck together at all sorts of angles.
7 Graphite and diamond are different forms of the element carbon. Graphite and diamond have different properties. The structures of graphite and diamond are shown below. Graphite Diamond 7 (a) Graphite is softer than diamond. Explain why.
Apr 20, 2014 · Compounds of metals do not conduct electricity as a solid, but metals are good conductors of electricity. > An electric current consists of the movement of charged particles. Compounds of metals are salts. They consist of oppositely charged ions. For example, NaCl consists of Na⁺ and Cl⁻ ions arranged in a crystal lattice. The ions in the crystal cannot move, so solid NaCl does not conduct ...
