Is silicon a crystal?
It is very easy to cut, however it would be difficult to cut into a desired shape. When you cut silicon you score it slightly then press it against an edge. However, it only breaks along the crystal lattice since silicon is usually available as a single crystal wafer. This means that you can only make clean breaks in the material. It does not "cut", you can only break it into pieces.
Silicon Ingot: A large, cylindrical, single crystal made from purified silicon. The cylinder is sliced into thin wafers which are used for making computer chips. Silicon Wafer: Intel uses wafers of pure silicon cut from a silicon ingot to make microprocessors. Silicon, the primary ingredient of beach sand, is a semiconductor of electricity. Semiconductors are materials that can be altered to be either a conductor or an insulator.
Computer chips are built on a slice of silicon. Silicon forms the basis of transistors which make up a complete circuit. The circuit is photo etched onto the silcon forming complex circuits containg transistors, resistors, capacitors and diodes. The silicon is grown as a single crystal. The crystal is then sliced into thin wafers, onto which the circuit is etched. These resemble a sliced potato or CHIP.
The bond energy of Si -C is generally considered to be lower than that of the C-C, so a simple explanation is that diamond has a stronger bond. Both diamond and silicon carbide have a three dimensional network structure. Diamond consists of tetrahedral bonded carbon atoms whereas silicon carbide has many polymorphs (crystal structure which are temperature dependant). As you heat silicon carbide up the crystal structure changes. Silicon carbide does not melt "congruently" to…
