An Overview of Ceramic Art

The word Ceramics is derived from the Greek word Keramos which means potter's earth or clay, however, the earliest ceramic things are dated from twenty-seven thousand years ago. Therefore, ceramics may be considered to be material made from naturally occurring clay or earth. Thus a ceramic is an inorganic solid made by the action of heating and subsequent cooling of a material. To put it simply, ceramic is a material utilized to create stuff. It's an all-encompassing term that covers any substance composed of inorganic crystalline materials. Ceramic is versatile stuff that's as old as civilization itself but still has numerous practical uses today.

Ceramic has evolved from simple grey clay pottery to glazed and finished materials in lots of styles and colors. Today ceramic items can be bought in anything from building components to art items. During the twentieth century, new ceramic components had been invented for use in advanced ceramic engineering such as in semiconductors.

The various properties of ceramics are discussed below-

1. MECHANICAL PROPERTIES- they are crystalline or amorphous and are usually covalently bonded or iconic substances. Ceramic materials also show plastic deformations.

2. ELECTRICAL PROPERTIES- they are semiconductors, and most of them are transitional metal oxides. However, under shallow temperatures, some ceramics become superconductors.

CLASSIFICATION OF CERAMICS:

They are classified as non -crystalline and crystalline ceramics. The non-crystalline ceramics are formed from melts and are called glass ceramic. They are produced after a great range of processing whereas the crystalline ceramics do not require much doling out.

Apart from the ones discussed above, ceramics have a wide range of usage

1. It is used for making knives, and ceramic knives are sharper than steel knives. Though they are brittle, their blades are more durable.

2. Ceramics like alumina and boron carbide are used as "Small Arms Protective Inserts."

3. Steel can be replaced by ceramic balls in ball bearings. Due to their hardness, they have a longer lifetime. Their electrical insulating capacities are also valuable in bearings, but a major drawback is their high cost.

4. Ceramic engines can be used in laboratories due to their high fuel efficiency, and they do not need any cooling system. However mass production is not possible because cracks can easily develop in ceramics which may result in dangerous equipment failure.

5. Nowadays bio-ceramics are made which include synthetic bones and dental implants.

6. High tech ceramic is also employed in making watch cases.

Types of ceramics

People first started making ceramics thousands of years ago (pottery, glass, and brick are among the oldest human-invented materials), and we're still designing brand new ceramic materials today things like catalytic converters for today's cars and high-temperature superconductors for tomorrow's computers. There's quite a big difference between age-old, general-purpose ceramics like brick and glass and modern, engineered ceramics that are sometimes designed for a single, specific purpose, such as filtering soot from a truck's dirty diesel engine or making a drill bit that lasts five times longer. That's partly why materials scientists like to divide ceramics into two kinds: traditional, and advanced (or engineering) ceramics.

Bricks, pottery, glass, porcelain, tiles, cement, and concrete are our classic, time-tested ceramics. Although they all have different uses, we can still think of them as general-purpose materials. Take tiles, for example. We can put them inside our homes or outside; on the walls, the floors, or the roof; and we can stick glass in our windows or poke away at it on our smartphone screens we can even drink champagne out of it. Ceramics like this are ancient materials ones our ancestors would recognize that have gradually found more and more uses as the centuries have worn on.

Hence, ceramics are employed almost everywhere and can be found in the most uncommon locations. For example, ceramics are being used in dental implants. That's because these components bond easily to the bone as well as other tissues within the body without rejection. Watchmakers are now creating high-tech white ceramic watches because of the materials lightweight, resistance to scratches, and overall strength. Because of their light, yet strong structure, ceramics are also usually utilized in bullet-proof vests as an approach to repelling high caliber gunfire. Even certain knife blades use ceramic components to be sure the blade remains sharper longer compared to traditional steel.

From its very humble origins as being material to make clay pots, to the advanced scientific applications of today, ceramic has come a long way. You may be amazed the number of ceramic things you locate while searching your house, from the white ceramic vase in the corner to the tiles that line the floor in your kitchen. Ceramic is all over the place and undoubtedly will continue to play an important part in our lives for years to come.
