Zirconia ceramics is second to the alumina ceramics in advanced ceramics application. Their following properties make this material as an important engineering material.

Very high melting temperature
Very low thermal conductivity
Very high strength
Excellent Chemical inertness
Very high hardness
Very high toughness
Very high refractive index

Zirconium oxide exists in three polymorphic forms:
1) Monoclinic
2) Tetragonal
3) Cubic
The monoclinic […]
