Properties of diamond graphite and fullerenes
WebThis field has expanded greatly in the last three decades stimulated by many major discoveries such as carbon fibers, low-pressure diamond, and the fullerenes. The need for such a book has been felt for some time. These carbon materials are very different in structure and properties. Some are very old (charcoal), others brand new (the fullerenes). WebPhysical Properties of Diamond It is extremely hard It has a very high melting point It has a high relative density It is transparent to X-rays It has a high value of the refractive index It is a bad conductor of electricity It is a good conductor of heat It is insoluble in all solvents Other Carbon Allotropes Buckminsterfullerene
