A crystal of pure alumina is transparent and colorless, but when we add a small amount of chromium, it creates a special defect, resulting in a beautiful red ruby crystal. In the processing of Si crystals for microelectronics, we add very small concentrations of P or B atoms to Si. These additions create defects in the arrangement of atoms in silicon that impart special electrical properties to different parts of the silicon crystal. The effect of point defects, is not always desirable. When we want to use copper as a conductor for microelectronics, we use the highest purity available.

Aluminium is a very shiny metal with a silver-white colour with a blue tint. It is light weighted but a strong metal. It is a very soft metal making it very easy to shape. Aluminium has a hardness of 2.75. This means it is hard enough to scratch your fingernail but soft enough to be scratched by a penny.
7. Diorite Diorite is a coarse-grained igneous rock intermediate in composition between granite and gabbro. It can sometimes be described as a "white granite" because of the abundance of albite, a white feldspar. Depending upon the amount of iron rich minerals present, diorite can range from nearly white to quite dark. Diorite has the same mineral content as andesite.

1.1 Microstructures When metals are in solid form they are crystalline. The crystal structure of a metal refers to the internal structure or arrangement of atoms in an ordered, repeating or three dimensional patterns. Normal metallic objects contain a collection of very small crystals which makes them polycrystalline. These crystals are grains. Casting is an example of a metallic object which has large grains that can be resolved with the naked eye and these structures are referred to as macrostructures (Copper Development Association Inc, 2013).
Once cooled it is generally a solid and transparent material that can be used in numerous applications. Unlike other materials that are made with a similar process (eg. Metals) “glass lacks the crystalline structure normally associated with solids, and instead retains the random molecular structure of a liquid.” (Dan Klein, 1984) As glass cools it gradually solidifies until r... ... middle of paper ... ...ble and is more energy efficient to make. Glass can be transparent, coloured, or opaque, and any shape that a craftsman can dream of. it can be turned into thread and woven, or be extremely hard and difficult to break and in case it is damage can be manufactured to crack, break into shards or safely crumble into pebbles.
