What is Ceramic?

Ceramics are classified as inorganicand nonm etal l ic mater ialsthat are

essential to our daily lifestyle.

Ceramics are generally made by takingmixtures o f clay, earthen

elements, powders, and waterandshaping them into desired

forms. Once the ceramic has been shaped, it is fired in a high temperatureoven known as a kiln.

Ceramics are all around us. This category of materials includes things like

t i le, bric ks, plates, glass , and to ilets.

History of Ceramics

The word "ceramic" comes from the Greek word (keramikos), "of

pottery" or "for pot tery", from (keramos), "po tter 's clay, t i le, po ttery"

Ceramics have been around for thousands of years with their proof in some

excavat ionsofanc ient tom bsand cit ies.

The ceramics we know today date back to around 24,000 BCwhen the f i rs t clay

animals and po tterywere found. It is believed that these were used in r i tuals

during that time and were very sacred.

As civilization moved forward and people needed certain utensi ls, ceramics

made a very good tool.

About 10,000 year slater there were many people who used tiles in Mesopotamia

and India and there were many vessels used for water and food s torage. Thisactually became an invention that was based on need.

The earliest ceramics were pottery objects or 27,000 year old figurines made

from clay, either by itself or mixed with other materials, hardened in fire

In the 20th century, new ceramic materials were developed for use inadvanced ceramic engineering; for example, in semiconductors.

The word "ceramic" comes

from the Greek word

(keramikos), "of

pottery" or "for pottery",from

(keramos), "potter's

clay, tile, pottery".

Types and applications of

Ceramics:

1. Structu ral clay products (the word structural here does

not mean load-bearing, but means used for building

con struc t ion, ei ther for load-bear ing or non -

loadbear ing/aesthet ic pu rposes)

-ceramic products intended for use in bui ld ing

const ruct ion. There is a wide variety of structural clay products,

broadly classified as facing materials, load-bearing materials,

paving mater ia ls, roof ing t i le, and chemical ly resistant

materials.

2. Wh itewares

- any of a broad

class of ceramic products

that are white to off-white in

appearance and frequentlycontain a significant vitreous,

or glassy, component.

3. Refractor ies

- any material that has an unusually

high melting point and that maintains its

structural properties at very high

temperatures. Composed principally ofceramics, refractories are employed in

great quantities in the kiln/ovens,

metallurgical, glassmaking, and ceramics

industries.

Fireclay bricks

4. Glasses

-In some glasses it is possible to bring

about a certain degree of crystallization in

the normally random atomic structure.

Glassy materials that exhibit such astructure are called glass ceram ic.

5. Abrasiv es

-sharp, hard material used to wear away

the surface of softer, less resistant

materials. Also used in grinding, cutting,

polishing, lapping, or pressure blasting

of materials. Classifications are Natural

and Synthet ic.

Natural:

Garnet Diamond

Synthetic:

Silicon carbide

7. Ad vanced c eram ics

-substances and processes used in the

development and manufacture of ceramic
