Inorganic, non-metallic materials made from compounds of a metal and a non-metal. Ceramic materials may be crystalline or partly crystalline. They are formed by the action of heat and subsequent cooling. Clay was one of the earliest materials used to produce ceramics, as pottery, but many different ceramic materials are now used in domestic, industrial and building products.

Scope and Importance
Ceramic engineering is the science and technology of creating objects from inorganic, non-metallic materials. This is done either by the action of heat, or at lower temperatures using precipitation reactions from high-purity chemical solutions. The term includes the purification of raw materials, the study and production of the chemical compounds concerned, their formation into components and the study of their structure, composition and properties.
Ceramic materials may have a crystalline or partly crystalline structure, with long-range order on atomic scale. Glass ceramics may have an amorphous or glassy structure, with limited or short-range atomic order. They are either formed from a molten mass that solidifies on cooling, formed and matured by the action of heat, or chemically synthesized at low temperatures using, for example, hydrothermal or sol-gel synthesis.
The special character of ceramic materials gives rise to many applications in materials engineering, electrical engineering, chemical engineering and mechanical engineering. As ceramics are heat resistant, they can be used for many tasks for which materials like metal and polymers are unsuitable. Ceramic materials are used in a wide range of industries, including mining, aerospace, medicine, refinery, food and chemical industries, packaging science, electronics, industrial and transmission electricity, and guided light wave transmission.
Ceramic materials are brittle, hard, and strong in compression, weak in shearing and tension. They withstand chemical erosion that occurs in an acidic or caustic environment. In many cases withstanding erosion from the acid and bases applied to it. Ceramics generally can withstand very high temperatures such as temperatures that range from 1,000 °C to 1,600 °C (1,800 °F to 3,000 °F). Exceptions include inorganic materials that do not have oxygen such as silicon carbide. Glass by definition is not a ceramic because it is an amorphous solid (non-crystalline). However, glass involves several steps of the ceramic process and its mechanical properties behave similarly to ceramic materials.
Crystalline ceramic materials are not amenable to a great range of processing. Methods for dealing with them tend to fall into one of two categories - either makes the ceramic in the desired shape, by reaction in situ, or by "forming" powders into the desired shape, and then sintering to form a solid body. Ceramic forming techniques include shaping by hand (sometimes including a rotation process called "throwing"), slip casting, tape casting (used for making very thin ceramic capacitors, etc.), injection moulding, dry pressing, and other variations.
Non-crystalline ceramics, being glasses, tend to be formed from melts. The glass is shaped when either fully molten, by casting, or when in a state of toffee-like viscosity, by methods such as blowing to a mold. If later heat-treatments cause this glass to become partly crystalline, the resulting material is known as a glass-ceramic.Market Analysis:
Asia-Pacific is the biggest as well as the fastest growing advanced ceramics market, having a significant share of around 40% of the global market in 2014. The market patterns of advanced ceramics and its various products are continuously showing an upward trend, which is mainly due to the increasing IT and electronics industries. China followed by India is the leading countries and the fastest growing markets in the region and also across the globe closely followed by the U.S. in terms of consumption.
Among various major product types of advanced ceramics, monolithic ceramics dominated the market with more than 60% of the total advanced ceramics market share in 2014. Ceramic matrix composite is another major product segment and is expected to grow significantly, from 2015 to 2020. Other product types of advanced ceramics include ceramic coating which is also expected to grow at a considerable rate in coming years.
International symposium and workshops
Ceramics and ceramic composites continue to attract growing attention as the key enabling materials for the safer and sustainable nuclear energy and for future fusion energy systems. This symposium provides a venue for material scientists and nuclear engineers to discuss the opportunities and needs for advanced ceramics and composites in such energy systems, and the current state-of-the-art science and technology of these materials ranging from materials design, processing and properties to their performance in harsh nuclear environments.
