What is a ceramic material?
a type of material that is typically an oxide, nitride or carbide of a metal
a type of material that is typically an oxide, of a high yielding polymer
a type of material that is typically an oxide, nitride or carbide of a non-metal
a type of material that is typically able to withstand high temperatures
Which answer is correct?
Ceramic material are typically hard wearing with excellent conductance so they are electrical and thermal conductors and withstand high temperatures.
Ceramic material are typically very hard with excellent resistance to corrosion. They are good electrical and thermal insulators and withstand high temperatures.
Ceramic material are typically very soft with minimum resistance to temperature. They are good electrical and thermal insulators and withstand high temperatures.
Ceramic material are typically very malleable with excellent resistance to weathering. They are good electrical and thermal conductors and as such withstand high temperatures.
