This document discusses ceramic fibers, including their definition, properties, and applications. Ceramic fibers are inorganic, crystalline materials made from metal and non-metal compounds. They have properties like high compressive strength, good dimensional stability, and high melting points. Ceramic fibers are used in glass, ceramics, electronics, textiles, aerospace, and other industries due to their heat resistance, strength, and durability. Some key applications include armor, engine components, brake discs, insulation, and bulletproof vests.

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.

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.
