Environmental Deterioration Of Ceramic Materials

Ceramic engineering and science proceedings volume 16 issue 5 summary.

Environmental deterioration of ceramic materials.

Ceramic materials can be deteriorated when they are exposed to freezing temperatures. Improper handling shipping storing or displaying and the accidental cracks and breakages caused by these are one of the major sources of deterioration of ceramics and glass. Deterioration of natural building materials like stone e g. Careless or uninformed cleaning of food stains grease and dirt can cause physical deterioration of ceramic and glass pieces.

Freshwater and coarse limestone is subject of numerous studies e g. Materials science general introductory materials science ceramic engineering and science proceedings proceedings of the 19th annual conference on composites advanced ceramics materials and structures b. Ceramic materials can be deteriorated by molten salts when exposed at high temperatures. It is in the nature of all the materials used for construction to eventually degrade and deteriorate.

Ceramic materials experience degradation polymers may dissolve when exposed to a liquid solvent. Ceramic materials are relatively resistant to deterioration which usually occurs at elevated temperatures or in extreme environments. Environmental degradation of advanced and traditional engineering materials is a monumental work for the field providing comprehensive coverage of the environmental impacts on the full breadth of materials used for engineering infrastructure buildings machines and components. There are several ways in which ceramics break down physically and chemically.

They may also absorb the solvent ans swell. Degradation of an object occurs as a result of the interaction between the environment or with the materials that form the object however in the case of ceramics environmental factors are the major cause. Deterioration of concrete is a gradual and irreversible permanent erosion of its basic properties leading to its disintegration. The molten salts may be already present in the clay used or may enter the clay body through environment.

The degradation of ceramics as a result of the interaction between the environment or with the materials that form the object however in the case of ceramics environmental factors are the major cause. Sulfur dioxide nitrogen oxides soot dust on man made silicate based materials ceramic glaze glass etc. This phenomenon can be observed in ceramics materials buried underground.
