ENGINEERING MATERIALS:
➢Engineering materials refers to the group
of materials that are used in the
construction of manmade structures and
components.
➢The primary function of an engineering
material is to withstand applied loading
without breaking and without exhibiting
excessive deflection.
➢The major classifications of engineering
materials include metals, polymers,
ceramics, and composites.
Sustainable Materials: Ceramics
It is eco-friendly in nature.
How are ceramics produced?
➢Ceramics generally start with a clay-based material, then fired at
high-temperature in a large industrial oven called a kiln.
➢ Firing is what most ceramics have in common.
➢These four basic processes — digging the raw material from the
ground, adding water, shaping, and firing — have been used to
make ceramics for thousands of years
Properties of ceramics
➢High melting points (so they're heat resistant).
➢Great hardness & strength.
➢Considerable durability (they're long-lasting and hard-wearing).
➢Low electrical & thermal conductivity (they're good insulators).
➢Chemical inertness (they're unreactive with other chemicals)
Spellbinding Uses of Technical
Ceramics
◦ In Space Exploration◦ insulating properties, high heat resistance, enhanced strength, and superior corrosion resistance.
◦ In International Thermonuclear Experimental Reactor◦ High insulating capabilities
◦ In Deep Sea Earthquake Observation◦ Submarines, glass was used to make pressure-resistance containers. Silicon Nitride and ceramic
material have greater corrosion resistance capability, condensing strength, and low specific density, can
resist more pressure than glass.
◦ So, Scientists are able to install seismograph at the depth 36,089 ft. to observe deep-sea earthquakes.
Ceramic layers were used, when space shuttle comes down The face of
Space shuttle get deform and (melt) due to high density and pressure.so ,
They were using ceramic layer.
