Ceramic Engineering/ Technology
Ceramic is a broad term used to describe natural and synthetic materials with mostly crystalline structure (ordered structure). They are materials made from compounds of a metal and a non-metal that are used widely for making household utensils to spacecraft, as heat-resistant material. The word 'ceramic' is traced back to the Greek word ‘keramikos’ meaning pottery, which is said to be derived from the Indo-European word ker, meaning heat. The ceramic industry covers everything from the small scale craftsman selling clay pots to the international corporation that supplies a line of semiconductors. Throughout history, ceramics has played an important role in industry and in everyday life as it was used to produce art, for storage of food and even currency, and the industry is expanding more and more with each and every major improvement in technology.
In the early days, ceramic industry manufacturers depended only on natural products, i.e basic earth and clay and soon advanced to quartz, stone and porcelain, which offered enhanced durability and strength. Eventually, they began to develop inorganic substitutes for these natural products like silicide, oxide, fiber-reinforced ceramics etc. The field of nanotechnology also opened new doors for the ceramic industry, as manufacturers seek materials that can be used in impossibly small-scale applications. Because of the strength, durability, tailor made properties, longer life, lower costs and non-metallic properties of ceramic, a large percentage of electronics goods, medical equipments and thousands of other items make use of its application. Ceramics can offer many of the advantages of metal without the thermal and electrical current transfer associated with metallic products.
Products within the ceramic industry can be classified as four basic types namely :
- Household Ceramics or White ware goods - includes crockery, pottery, porcelain, etc.
- Structural Ceramics - includes those used in the construction industry, such as bricks, pipes, floor, roof tiles, etc
- Refractory Ceramics - consists of things like furnace liners, glass products, abrasives, etc.
High-performance Technical Ceramics (Engineered Ceramics) - includes things like ceramic brake pads, dental implants, semiconductors, etc.
Ceramic Engineering alias Ceramic Technology is the branch of Materials engineering and science that deals with the properties, manufacturing, designing and applications of ceramic materials. It is the science and technology of creating objects from inorganic, non-metallic materials either by the action of heat, or at lower temperatures using precipitation reactions from high purity chemical solutions. Ceramic Engineering/ Technology also deals with the purification of raw materials, the study and production of the chemical compounds concerned, their formation into components and the study of their structure and composition. Ceramic technology is useful in many ways - to protect the internal electric boards from short circuits and other mishaps; for making innovative, ultra-fast computer systems by using ceramic superconductors, lasers, and glass optical fibers; to develop components for fiber optic cables that allow doctors to examine the inner organs of the human body.
Artists and craftspeople concerned with the creation of pottery and sculptures are called ceramicists. Those who deal with the study, research and development of the ceramic materials are termed as Ceramic Engineers/ Ceramic Technologists. Ceramic technologists are specialists who study the heat-resistant materials, their behavior, application, and use. They use the basic principles from chemistry, physics and material science for analyzing, designing, manufacturing and maintaining ceramic systems. They work with a wide variety of products, ranging from glassware and electronic components to nuclear reactors and linings for blast furnaces and jet engines. The role of a Ceramic Engineer is enormous in various branches of engineering such as Electrical Engineering, Materials Engineering, Chemical Engineering, Mechanical Engineering, and many others. They develop different kinds of material required for Satellites, Nuclear Reactors, Commercial Establishments and Scientific Establishments and even pollution control devices. Engineers also develop heat tiles using ceramic material to protect space shuttles and the future supersonic space plane from the burning heat of re-entry into the earth’s atmosphere.
Ceramic and Ceramic technology has developed over time and are being used in almost all traditional as well as advanced everyday applications. Traditional applications of ceramic technology include consumer products like dinnerware or ovenware and construction products like tile or windows, etc. Advanced applications take advantage of specific mechanical/ electrical/ optical/ biomedical/ chemical properties of glass or ceramic materials and have entered the scene over the last several decades or so. In India, the ceramics industry is growing at a compound annual growth rate (CAGR) of about 15% with a lot of job opportunities. Recent advances in technology have expanded the applications of ceramic engineering.
How to become a Ceramic Engineer
Those who intend to become a ceramic engineer/ ceramic technologists must have an engineering degree in ceramic engineering.

Candidates from streams like Mechanical/ Civil/ Electrical/ Chemical and Materials engineering can also become a ceramic engineer.
After graduation, students who are interested to do higher studies can join the 2 years postgraduate program (M.E/ M.Tech) in Ceramic engineering. Those with B.E/ B.Tech in Ceramic/ Chemical/ Mechanical/ Electrical/ Manufacturing or other related field can apply for master's degree. Admissions are based on the marks obtained in the graduation level. But in some institutes, the selection is based on GATE score. After post graduation, one could go for research and opt for Ph.D/ M.Phil.
Besides professional engineering degree, there are numerous polytechnics in India that offer 3 year diploma in Ceramic Engineering. Eligibility for diploma program is a pass in 10th std board exam with at least 50% marks.
