Ceramics Physical Science

A ceramic material is classed as

• A metallic material but non organic material

• A non metallic, non organic material

• A clay pot

• A non metallic, non polymer material

Which set of properties are commonly associated with ceramic materials.

• Good toughness, good conductivity and light weight.

• High levels of hardness, good conductivity and light weight.

• Nice colours

• High levels of hardness, high levels of heat resistance and quite brittle.

Which of the following is not a ceramic material?

• Glass

• Silicon nitrite

• Bakelite

• Silicon carbide

The atoms in many ceramic materials use which bonding mechanism to hold together?

• Pritt stick

• Metallic

• Ionic

• Chain linked

A common micro structure found in ceramic materials is a

• Crystalline structure

• Grain structure

• Chain structure

• pretty pattern

Which of the following processes is not associated with the manufacture of ceramic products?

• Welding

• Sintering

• Slip casting

• Powder forming

Of the following products which one would you not think was made from a ceramic material?

• Tap washer

• carving knife

• Heat shield

• Electronic resistor

• Car wheel

Which of the following is not a category of ceramic materials?

• Glass

• Traditional ceramics

• Cements

• Industrial ceramics

• Registered ceramics

Select two reasons why the given product would be made from a ceramic material.

• It would be cheap so keeping costs down..

• If it was to be used in an erosive environment.

• If it was to be subjected to high levels of impact.

• For ease of manufacturing

• If it was to be used in high temperatures.

Although ceramic materials have a good range of important properties one limitation to their use is that they are often

• Too malleable

• Too brittle

• Too ductile

• Too light
