Ceramics

Which of the following is (are) property(ies) of ceramic?

• brittle

• heat-resistant

• corrosion resistant

• all of the above

High-fired ceramics, like stoneware and porcelain, were first produced by what culture?

• Romans

• Vulcans

• Greeks

• Chinese

Ceramic materials are weak in

• shearing

• tension

• both (shearing) and (tension)

• compression

Answer explanation

Ceramics are typically hard and brittle. While their strength in compression is very high, they are not suitable for loading in tension. Their brittle qualities mean that they fracture very easily. In compression, a crack is not easily propagated, but in tension the crack is free to grow.

Ceramic materials are

• inorganic and non metallic

• low hardness

• ductile and malleable

• magnetic and wear resistant

Ceramics are usually good...

• electrical conductors

• electrical and thermal insulators

• dimensional tolerances

• for fashion industry

Glasses have property(ies) such as

• crystalline structure

• ductile

• transparency and hardness

• high tensile strength

Which of the following ceramic materials comes under the category of traditional ceramics?

• tungsten carbide

• titanium carbide

• silicone carbide

• alumina

Answer explanation

These are usually based on clay and silica

Advanced ceramics are also referred to as

• rapid prototyping

• traditional ceramics

• superior ceramics

• engineering ceramics

Refractory ceramics often in the form of

• coating

• bearing

• bricks and filters

• cutting tool

Below are some types of ceramics except?

• Silicate ceramics

• Oxide ceramics

• non-oxide ceramics

• tungsten ceramics
