Ceramic Material Molecular Structure

Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula al 2 o 3 it is the most commonly occurring of several aluminium oxides and specifically identified as aluminium iii oxide it is commonly called alumina and may also be called aloxide aloxite or alundum depending on particular forms or applications.

Ceramic material molecular structure.

Generally ceramic particles are fine and coarse. Electronic structure and atomic bonding determine microstructure and properties of ceramic and glass materials. Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics. This is why ceramics generally have the following properties.

Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. We determine the above all properties with the particle sizes of the material.

The toughness strength and translucence of porcelain relative to other types of pottery arises mainly from vitrification and the formation of the mineral mullite within the body at. High hardness high compressive strength and chemical inertness. Nonconductivity arises from the lack of free electrons such as those found in metals. These are very important parameters for the ceramic material.

The two most common chemical bonds for ceramic materials are covalent and ionic. In ionically bonded ceramics bonding electrons are accepted by the electronegative elements such as oxygen and. Ceramic composition and properties ceramic composition and properties nonconductivity. Therefore the structure the metallic atoms the structure of the nonmetallic atoms and the balance of charges produced by the valence electrons must be considered.

For a ceramic material to be used as a biomaterial it must have adequate physical biological and mechanical properties to perform its function. The density of ceramics is intermediate between polymers and metals. The bonding of atoms together is much stronger in covalent and ionic bonding than in metallic. Crystalline materials have high density than non crystalline materials.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramic crystalline or partially crystalline material most ceramics usually contain both metallic and nonmetallic elements with ionic or covalent bonds. Ordinarily ceramics are poor conductors of electricity and therefore make excellent insulators. It occurs naturally in its crystalline polymorphic.

The major challenge facing the use of ceramics in the body as permanent implants is to replace old deteriorating bone with a material that can function for the remaining years of the patient s life.
