Ceramics giant molecular structure.

Ordinarily ceramics are poor conductors of electricity and therefore make excellent insulators. 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. For example alumina al2o3 is a compound made up of aluminum atoms and oxygen atoms. A ceramic is an inorganic non metallic solid which is prepared by heating a substance or mixture of substances to a high temperature.

In ionically bonded ceramics bonding electrons are accepted by the electronegative elements such as oxygen and. Glass ceramics are made of small grains surrounded by a glassy phase and have properties in between those of glass and ceramics. The two most common chemical bonds for ceramic materials are covalent and ionic. This is called a compound.

Giant structure occurs in ionic and covalent compounds. Nonconductivity arises from the lack of free electrons such as those found in metals. Ceramics often contain silicon dioxide magnesium oxide and aluminium this gives ceramics their giant covalent or ionic structures. Basically we can divide chemical structures into two types.

Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. The bonding of atoms together is much stronger in covalent and ionic bonding than in metallic. Most ceramics are made up of two or more elements.

Amorphous structure means that atoms are not organized according to a well ordered repeating arrangement as in crystals.
