Understanding the Differences Between Alumina, Zirconia, and Silicon Carbide Ceramics

Choosing the right technical ceramic material depends on application-specific properties such as hardness, wear resistance, and thermal stability.

Comparison Chart:

Property	Alumina	Zirconia	Silicon Carbide
Hardness	High	Medium	Extreme
Toughness	Medium	High	Medium
Thermal Resistance	High	High	Extreme
Wear Resistance	High	Very High	Extreme

Applications:

• Alumina ceramics for electronic substrates and insulation.

• Zirconia ceramics for precision machinery and medical applications.

• Silicon carbide ceramics for aerospace and high-temperature industries.
