Ceramics Giant Molecular Structure

Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids.

Ceramics giant molecular structure.

Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics. Basically we can divide chemical structures into two types. For example alumina al2o3 is a compound made up of aluminum atoms and oxygen atoms. Metals also have a giant chemical structure whether the metal is pure or an alloy.

Ordinarily ceramics are poor conductors of electricity and therefore make excellent insulators. A ceramic is an inorganic non metallic solid which is prepared by heating a substance or mixture of substances to a high temperature. Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. Most ceramics are made up of two or more elements.

Ceramics often contain silicon dioxide magnesium oxide and aluminium this gives ceramics their giant covalent or ionic structures. Glass ceramics are made of small grains surrounded by a glassy phase and have properties in between those of glass and ceramics. Amorphous structure means that atoms are not organized according to a well ordered repeating arrangement as in crystals. The bonding of atoms together is much stronger in covalent and ionic bonding than in metallic.

The table below provides a summary of the main properties of ceramics and glass. Contains a huge number of atoms or ions arranged in a particular way but the number of particles is not fixed the ratio might be fixed but not in all cases. Nonconductivity arises from the lack of free electrons such as those found in metals. This is called a compound.

Giant structure occurs in ionic and covalent compounds.
