Description

Zirconium Oxide (Monoclinic) is a form of zirconia found in the monoclinic phase of zirconia crystals. This form is known for its high-temperature resistance and mechanical properties, but its stability changes with temperature. Monoclinic zirconia is typically used in high-temperature applications and in challenging industrial conditions. The monoclinic phase exhibits lower thermal stability and higher expansion compared to other zirconia phases, making it preferable in specific temperature ranges. Monoclinic zirconia’s strong mechanical properties and durability make it suitable for metalworking, ceramic production, and industrial applications. It can also be used in biomedical applications, such as dental prosthetics and other implants.

  2. Tetragonal Phase (T):
    • Stable between 1170–2370°C.
    • Crucial for durability and fracture toughness. Can be stabilized at lower temperatures with stabilizers (e.g., yttria).
  3. Cubic Phase (C):
    • Stable above 2370°C.
    • Exhibits high electrical conductivity, making it valuable for fuel cells and electrochemical applications.
