. What are the properties of ceramic materials?
Answers
Answer:
High melting points
high hardness and strength.
Considerable durability
Low electrical and thermal conductivity
They are chemically inert.
Explanation:
the most important general property of ceramics is that they're refractory: they're rough-and-tumble materials that will put up with fair amounts of abuse in the most ordinary and extraordinary situations. Just consider, most of us tile our kitchens and bathrooms because ceramic tiles are hard, waterproof, largely resistant to scratches, and keep on looking good for year upon year; but engineers also put (very different!) ceramic tiles on space rockets to protect them against heat when they whiz back to Earth.
If we're summarizing their properties, we can say that ceramics have:
High melting points (so they're heat resistant).
Great hardness and strength.
Considerable durability (they're long-lasting and hard-wearing).
Low electrical and thermal conductivity (they're good insulators).
Chemical inertness (they're unreactive with other chemicals).
Most ceramics are also nonmagnetic materials, although ferrites (iron-based ceramics) happen to make great magnets (because of their iron content).
Those are the useful points, but, thinking about traditional ceramics like glass or porcelain, you'll also have noticed one major drawback: they can be fragile and brittle, and they'll smash or shatter if you drop them (subject them to "mechanical shock") or suddenly change their temperature ("thermal shock").
