Diamond vs. Graphite Diamond is composed of sp 3 hybridized carbon atoms that are a very stable allotrope of carbon. Covalent carbides include B4C3 and SiC (carborundum - an abrasive with a diamondlike structure). If a piece of graphite is connected into a circuit, electrons can fall off one end of the sheet and be replaced with new ones at the other end. Man has actually found out the process of diamond formation and also has

Graphite is a non-metal. crystal are arranged in a hexagonal ring in a solitary airplane. The allotropes of carbon have been covered in sufficient detail in Chapter 8. You might argue that carbon has to form 4 bonds because of its 4 unpaired electrons, whereas in this diagram it only seems to be forming 3 bonds to the neighboring carbons. This is because of the relatively large amount of space that is "wasted" between the sheets. Attractions between solvent molecules and carbon atoms will never be strong enough to overcome the strong covalent bonds in graphite. Graphite in its powdered form is used as a lube in heavy

Die zweidimensionalen Schichten des Graphits lassen sich leicht abspalten, denn die Bindung zwischen den einzelnen Schichten ist schwach (Van-der-Waals-Kräfte). Have questions or comments? In graphite you have the ultimate example of van der Waals dispersion forces. The planar structure of graphite allows electrons to move easily within the planes. Silicon dioxide is also known as silica or silicon(IV) oxide has three different crystal forms. For yellow light, for example, diamond has a high refractive index, 2.4, and a low critical angle of 24.5 degrees. These planar arrangements extend in two dimensions to form a horizontal, hexagonal "chicken-wire" array.
