Ceramics can be divided into two categories, which is...

• Modern ceramic & traditional ceramic

• Synthetic ceramic & natural ceramic

• Ttraditional ceramic & industrial ceramic

Two major types of oxide ceramics

what is alumina

• Aluminium Oxide

• Aluminium nitride

• Aluminium carbon

Aluminum oxide can be blended with small amounts of other ceramics, such as..

• silicon carbide and carbon

• silicon oxide and tittanium oxide

• tittanium oxide and tittanium carbide

What is zirconia

• Zirconium Oxide

• Zirconium Nitride

• Zirconium carbon

Partially stabilized zirconia (PSZ) has higher strength and toughness and better reliability in performance than does zirconia. how it can be obtained?

• By doping zirconia with oxides of calcium or magnesium

• By doping zirconia with carbon and aluminium

• By doping zirconia with carbon or magnesium

The reason for engineering ceramics is sensitivity to cracks, impurities, and porosity is?

The first methods to prestressing the shaped ceramic components subjects them to compressive stresses.

• Heat treatment and chemical tempering

• Laser treatment of surfaces

• Coating with ceramics having different thermal-expansion coefficients

• Surface-finishing operations (such as grinding) in which compressive residual stresses are induced on the surfaces

The second method to prestressing the shaped ceramic components subjects them to compressive stresses is

• Heat treatment and chemical tempering

• Laser treatment of surfaces

• Coating with ceramics having different thermal-expansion coefficients

• Surface-finishing operations (such as grinding) in which compressive residual stresses are induced on the surfaces

The third method to prestressing the shaped ceramic components subjects them to compressive stresses is
