Micro-structure of ceramic, polymer and composite material Assignment

Micro-structure of ceramic, polymer and composite material - Assignment Example According to Whitney (2000), ceramic structures come in a variety and each structure has its own unique properties. For instance, some are very high thermal conductors while some don’t conduct heat at all but they possess other properties. Micro structures of Ceramics also vary in nature as some are pure glass, some crystalline and others are a combination of the two. Ceramics with glassy structures have properties that differ from metallic structures, and the difference in these properties is the atomic structure of the glass (Russell, 2009). Silica is the most common products that makeup glass where when it is fused together then placed in cold temperatures; the glass is formed. The main advantage of ceramic glass is its ability to be made into different shapes when it is still a soft plastic. Ceramics in crystalline form have the metallic and non-metallic atoms which should be balanced for the crystals to be made. During the crystallization, the arrangements in ions mainly determine the manner in which cells will be arranged. Whitney (2000) outlines that crystal structures are neutral in nature and the structures are closely parked together. These ceramics combines the properties of other materials to create a complete product, and they are hard in nature and mechanically stable. According to (Russell, 2009) Nitride ceramics are mainly used to cut wood materials due to their hardness. The process of making nitride ceramics is an irreversible process because of the arrangement in the lattices that are interchangeable. One of the main disadvantages of ceramics is the presence of impurities in the metals, and this affects its formation. There are also some defects that affect the neutrality of the atoms and these defects are, as a result displacement of atoms from their positions, therefore, creating a vacuum. Other shortcomings of ceramics are the formation of solids that lack clear chemical formulae due to their
