Environmental Deterioration Of Ceramic Materials

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.

Environmental deterioration of ceramic materials.

Ceramic engineering and science proceedings volume 16 issue 5 summary. Ceramic materials are relatively resistant to deterioration which usually occurs at elevated temperatures or in extreme environments. Ceramtec ceramic components ensure long life for parts that are subject to high stress during conveying transport or the processing of raw materials minerals and resources or in the field of environmental technology for instance in water treatment or recycling and processing and recycling of waste. Ceramic materials can be deteriorated when they are exposed to freezing temperatures.

It is in the nature of all the materials used for construction to eventually degrade and deteriorate. Careless or uninformed cleaning of food stains grease and dirt can cause physical deterioration of ceramic and glass pieces. The study of concrete and building material deterioration and durability and the knowledge of these properties form thefundamentalbasisfortheevaluationofstructures thedurabilityofstructuresis influenced by many factors. 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 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. Freshwater and coarse limestone is subject of numerous studies e g. Ceramic materials can be deteriorated by molten salts when exposed at high temperatures.

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. Sulfur dioxide nitrogen oxides soot dust on man made silicate based materials ceramic glaze glass etc. Deterioration of natural building materials like stone e g. There are several ways in which ceramics break down physically and chemically.

2 however few studies are designed to research the effect of air pollutants e g. 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. They may also absorb the solvent ans swell.
