2. PRESENTATION TOPIC:
Properties and Uses of
Ceramic Fibers

3. Ceramic Fibers:
Definition: Ceramic fibers are inorganic, non-metallic materials made
from compounds of a metal and non-metal.
Ceramic fibers are 100% crystalline and have no amorphous region.

4. Properties of Ceramic Fibers
1-Mechanical Properties:
 Hard
 High Compressive Strength
 Brittle
 Good Dimensional Stability
 Low Density
 Low Tensile Strength

5. Properties of Ceramic Fibers
2-Electrical Properties:
• Very Good Thermal Resistance
3-Magnetic Properties:
 Non-Magnetic

6. Properties of Ceramic Fibers
4-Chemical Properties:
 Low weight
 Good Chemical Resistance
 Unreactive

7. Properties of Ceramic Fibers
5-Heat Properties:
 High Temperature Stability
 Low Heat storage
 High Melting Points
 Incombustible

8. Applications or Uses Of Ceramic Fibers
Three Basic Categories
 Glass-Ceramic Applications
 Traditional Ceramic Applications
 Advanced Ceramic Applications

9. Glass-Ceramic Applications
 Armoured Security Glass
• Due to High flexibility and
compressive strength.
 Container glass (bottles)
• Due to high compressive strength
and heat resistant.

10.  Dinnerware
• Due to thermal stability
and good dimensional
stability.
 Buildings
• Due to hardness, compressive
strength.

11. Traditional Ceramic
 Bricks
• Extreme hardness and crystal
structure.
 Cements(Concrete Roads, Bridges)
• It has high porosity, high stress
and high strength.

12.  Sanitary Wear
 Decorative Ceramics
 Floor and Wall Tiles
• Due to its high porosity, high
compressive strength and
hardness.

13. Advanced Ceramics
 Engine Component
Rotor(alumina) Gears(alumina)
oIn engines heat resistant ceramics are used to increase efficiency,
decrease noise and minimize wear.

14.  Ceramic Brake Disc
• Due to high temperature
resistance it is used in brake
discs.
 Mechanical Engineering
(Cutting Tools & Mechanical Pumps)
• High wear resistance, temperature
resistance and a high level of corrosion
resistance make tools safe.

15.  Electronics(Capacitors &
Insulators)
• Ceramics heat sinks provide the
right climate for high power
electronics.
 Medical Technology(Artificial
Bone and Teeth)
• Bio-compatible and wear resistant
advanced ceramics enables doctors
to provide patients with optimum
care.

16.  Energy and Environment
• Enables safe, low-wear process control.
• Ensure emissions and efficient uses of resources
in many areas.
 Aerospace Technology(Rocket Nozzles, Space
Shuttles, Missile-Nose-Cones)
• Shield missile internals from heat.
• Withstands and focuses the exhaust of the
rocket booster.

17. Textile(Fiber Paper, Insulating Lagging tapes, Bullet Proof Jackets, Blankets)
 Fiber Paper
• Paper is produced from high
purity ceramic fibers. It is noted
for its temperature resistance as
high as 2300º F.Used in Boiler
and Nuclear Reactor.
 Blankets
• Due to high temperature resistance,
Lightweight used in Insulation for
power plant, turbine, thermal
reactor and generator.

18.  Insulating Lagging Tapes
• Due to Chemical resistant, Low
thermal conductivity and
Lightweight used in Safety and
protective insulation covers, strip
curtains, door seals.
 Bullet Proof jackets
• Due to high compressive strength
used in bullet proof jackets for
protection.
