Ceramic materials are inorganic, non-metallic materials made from compounds of metals and non-metals. Ceramic properties are determined by the atoms present and bonding between them. Ceramics are widely used in construction materials like bricks and tiles as well as industrial applications due to properties like corrosion and heat resistance. Common ceramic materials include alumina and silicon nitride, and ceramics are used in products like dental implants, gas turbine engines, and cutting tools.

2. WHAT IS CERAMIC MATERIALS?
Ceramic materials are 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.

4. PROPERTIES
The properties of ceramic materials, like all materials,
are dictated by the types of atoms present, the types
of bonding between the atoms, and the way the atoms
are packed together. This is known as the atomic scale
structure. Most ceramics are made up of two or more
elements. This is called a compound. For example,
alumina (Al2O3), is a compound made up of aluminum
atoms and oxygen atoms.

5. REQUIREMENTS
Ceramic products for construction, domestic and industrial
uses are obtained making a wide use of natural raw materials.
Bricks, tiles, sanitaryware, tableware, lightweight aggregates
and silica-alumina refractories are all manufactured mainly
utilizing clay materials, feldspathic fluxes and/or quartzous
sands; in addition, complementary raw materials are seldom
used (e.g. talc, carbonates, wollastonite, zircon, borates,
lithium minerals).

6. IMPORTANCE OF CERAMICS IN TODAY'S
WORLD?
 Applications for advanced ceramics have received
major media attention in recent years, particularly
for use as parts in a future ceramic heat engine.
However, corrosion resistance, chemical inertness,
thermal shock resistance, and other properties that
materials scientists and engineers can design into
ceramic materials make both traditional and
advanced ceramics highly attractive in a large
number of applications

7. IMPORTANCE…………
 ceramics play a big role in the machine-tool
industry. Their thermal and mechanical stability
allows them to retain their smooth, accurate cutting
surfaces longer than metals do. Coated cutting
tools and inserts, some with as many as 12
extremely thin coatings, each designed to serve a
special function, can run productively at faster
cutting speeds and at faster feed rates than can
any metal-alloy tool in the machining of hard steels,
superalloys, and ceramics.

8. TYPES OF CERAMIC MATERIALS
• Alumina
Alumina is the most widely used advanced ceramic
material. It offers very good performance in terms of wear
resistance, corrosion resistance and strength at a
reasonable price. Its high dielectric properties are
beneficial in electronic products.
• Silicon
Silicon nitride exceeds other ceramic materials in
thermal shock resistance. It also offers an excellent
combination of low density, high strength, low thermal
expansion and good corrosion resistance and fracture
toughness.

9. USES OF CERAMIC MATERIALS
Ceramic products are hard, porous, and brittle. As a result,
they are used to make pottery, bricks, tiles, cements, and
glass. Ceramics are also used at many places in gas turbine
engines. Bio-ceramics are used as dental implants and
synthetic bones. Given below are some other important uses
of ceramics.

10. CONCLUSION………….
Civil Engineering's have a great impact on societies, they build
houses , roads , dams , irrigation , sanitary system , all these
services are mandatory for all societies , therefore civil engineers
significantly affect the countries and people
