 Ceramic Material, Types, Properties and Usage

What is Ceramic Material:-

Ceramic is an inorganic metallic or non-metallic compound that has been shaped and hardened by heating to a high temperature. The ceramic word comes from ‘Greek’ meaning 'Pottery' and includes materials like glass etc. Traditional ceramics pottery has been carbon dated 17000 years old. Traditional ceramics are clay-based. The category of ceramics is earthenware, stoneware, and porcelain. The composition of clay used, type of firing temperature, and temperature determine the nature of the end product.

Modern ceramic materials differ from the traditional materials which were only based on natural substances. It is now possible to prepare ceramics using a wide range of properties and area, this field has evolved as a very broad scientific and technical field in its own right. In practice, one encounters ceramics in practically all branches of materials science and the characteristics are so wide-ranging that the common basis of these substances is not always immediately apparent. All ceramic materials are prepared by ceramic technology, and powder substances are used as the initial raw materials. Their physical properties are an expression not only of their composition but primarily of their structure.

 

Ceramics,types and applications

 

Brief history of ceramics

·        23,000–25,000 BCE: Earliest use of human ceramics (for instance, in figurines of human beings and other animals fabricated from pottery, located at Dolní Věstonice within the Czech Republic).

·        14,000BCE: Ceramic tiles are being made in India and Mesopotamia.

·        18,000–14,000 BCE: Earliest use of pottery vessels (for example, in Jiangxi, China).

·        7500–6500BCE: First use of dust bricks.

·        6000 BCE: Earliest recognized kiln

·        5000–8000 BCE: First use of glazes. Nile Valley of Egypt. In step with

·        3500–5000BCE: Earliest use of glass (in line with Eric Le Bourhis in Glass: Mechanics and technology).

·        3500–2500BCE: Invention of the potter's the wheel.

·        Mid-overdue 1900s: improvement of powerful glass and ceramic insulators for telegraphs and electric-powered power distribution.

·        The 1940s: development of ferrite magnets for such things as loudspeakers and electric-powered cars.

·        1986: excessive-temperature superconductors determined via Georg Bednorz and k. Alex Müller of IBM.

Properties of Ceramic materials:

If I summarize I would say that the properties of ceramics are:

• High melting points
• Great hardness and strength.
• Considerable durability.
• Low electrical and thermal conductivity.
• Chemical inertness.
• Compressive strength
• High resistance to corrosion ,weather and environment
• High Dimensional stability
• High melting point
• Ceramics are non-magnetics

Ceramics,types and applications

What Are The Applications Of Ceramics?

·        Most advance Ceramics are used in oil free bearing

·        Ceramics are used in aerospace industry because of low weight compared to others

·        Ceramics are used in cutting tool(Because of hardness)

·        Ceramics are used as thermal insulators

·        Ceramics are used as electrical insulator (Ceramic insulation)

·        Ceramics are used in construction industry (Tiles, bricks)

·        Concrete is also ceramic material that is utilized in maximum buildings and different civil engineering programs.

·        White ware products: which include pottery, stoneware, satisfactory china, porcelain, other tableware, and so forth.

Conclusion

Ceramics are everywhere around us playing important role in our daily life. Ceramics are used in various thins and appliances.  Choosing the type of Clay is main step which define which type of ceramics product would be. Ceramics are also used in electrical application and thermal insulations. Ceramics are key product in our daily life like cooking vessels, pipes, toys and art foam.
