Not just china
From conventional sectors like steel and cement to technology-driven industries like electronics and communications, ceramic engineers lend their expertise to all, writes Rahat BanoUpdated: Jul 28, 2010 12:07 IST
Don’t think only of your gorgeous demitasse or, your washbasin and such common wares. For, ceramic engineering is much more than that — from lenses and artificial bones for humans to heat shields of rockets. This is where science and technology blends with art and craft.
And that’s a reason one youngster chose it as his calling. Says a ceramic engineer (who doesn’t wish to be named) working in a public sector steel-making company, “Along with technical things I had an inclination towards art and craft also. Ceramic engineering would satiate my urge for both.”
And it’s encouraging that this field of engineering finds applications in many sectors. The engineer adds, “Ceramic engineering deals with inorganic, non-metallic materials and some of them are very critical — such as fibre optic materials which play an important role in the telecommunications industry.
“Cell phones would not be possible without the development of electronic ceramics. Ceramic materials are stable at extremely high temperatures and, therefore, used in the protective lining of high temperature vessels like boilers, converters, furnaces, ladles etc.
“They are also compatible with the human body and are used to replace or augment damaged or diseased tissues.”
Employment options for ceramic engineers are diverse, he adds.
Says Prof Om Parkash, head, department of ceramic engineering, Banaras Hindu University, “There is hardly any branch of engineering which does not make use of these advanced ceramic materials.
“Any electronic device such as television, radio, tape recorders, computers, mobile phones use hundreds of components made from these. There are a large number of applications in the military, air force and navy which make use of devices / components, such as radar, in submarine, aircraft and space shuttles, made from these high-tech ceramics.
“The success of all other industries, such as metals and steels, automobiles, communications, depends on the satisfactory performance of ceramic components.”
Other areas where ceramic engineers play a role are conventional sectors developing value-added or innovative products.
Prof Parkash adds that these industries, such as tiles and glass manufacturers, “have R&D units for making products that serve multiple purposes. For example, tiles for the purpose of decoration are being developed, and these also act as sensors for various applications.”
So, what does it take to get there? Prof Parkash says, “A ceramic engineer must have a good background in basic sciences (physics, chemistry, maths and biology) coupled with an excellent experimental and design skills.
“A sound knowledge of computers helps in modelling a design before actual fabrication/construction is taken up.”
“Ceramic engineers must be able to solve problems and communicate their ideas to others. They should have skills in science and mathematics,” says the engineer
from the public-sector steel-maker. “Apart from a passion for engineering in general, an improved understanding of the specific ceramics materials is needed to become a good ceramics engineer.” And very importantly, this creative endeavour requires a hands-on approach.
What's it about?
Ceramics are inorganic non-metallic materials. Ceramic engineering refers to the processing and fabrication of components / devices / machines of ceramics for technological applications. There are two types of ceramic products:
Traditional: Products such as bricks, pottery, porcelain, sanitary ware, cement, concrete, refractories (materials which can withstand very high temperatures) and glasses of various kinds
Advanced ceramics: These are manufactured from highly purified materials which have controlled properties. Some examples are: high quality insulators and substrates for integrated circuit technology, memory cores in computers, over voltage protection devices (varistors), gas and humidity sensors, etc. Advanced ceramics can be classified depending on their applications as per their specific physical/chemical properties
Apart from manufacturing industries such as steel plants, glass and cement and aluminium industries, ceramic engineers may find openings in electronics, communications, optics, transportation, medicine, energy conversion and pollution control, aerospace, and the construction sector
The average day of a ceramic engineer (in an R&D organisation):
8.30 am: Plan the experimental and product development activity for the day
9.30 am: Start processing activities on shop floor, testing activity in lab and process improvement activities in ceramic units
1.30 pm: Lunch
2 pm: Consult library
3 pm: Record data on experiments, quality improvement and R&D work
4 pm: Analyse results
6 pm: Leave office for the day
BTechs/MTechs earn between Rs 3 lakh to Rs 9 lakh a year, in India. Salaries depend on your education and experience, the location and the type of job

Rating as per the demand is as given below:
. Wall and floor tiles
. High- and low-tension insulators
. Electronic ceramics
. Advance ceramics
According to you, what are the most important qualities and traits that an aspirant should develop to build a successful career in the field of ceramic engineering?
Be ready to work like a potter — working at the potter’s wheel.
What are the pluses and minuses of this profession?
Engineers who have specialised in ceramics have the opportunity to serve the country through their participation in industrial development, development of nuclear power sector and of the atomic energy sector, infrastructure development and energy efficiency improvements of the country.
Ceramic engineers are not paid well in the beginning of their careers like engineers in the software sector. Secondly, ceramic engineers do not have many openings in the government sector and in the Indian Engineering Services.
