Zirconia (Zirconium Oxide, ZrO₂) Ceramic Powder
Zirconia (ZrO₂) ceramic powder is a white, odorless refractory oxide with outstanding mechanical strength, fracture toughness, and thermal shock resistance. Thanks to its high melting point (~2715°C) and biocompatibility, zirconia is widely used in structural ceramics, plasma-sprayed coatings, oxygen sensors, and medical implants.
At Princeton Powder, we offer a range of high-purity zirconium oxide powders, including monoclinic, tetragonal, and nano zirconia, with customizable particle size distributions for sintering, additive manufacturing, or thermal spraying.

Zirconia (Zirconium Oxide) ZrO2 Ceramic Powder FAQ
What are the crystal phases of zirconia?
Zirconia exists in three primary phases:
- Monoclinic (stable at room temperature)
- Tetragonal (requires stabilization, e.g., Yttria)
- Cubic (used in YSZ systems)
Each phase has different mechanical and thermal characteristics. Tetragonal zirconia is often preferred for its strength and toughness.
Do you offer stabilized zirconia (YSZ)?
Yes. We offer Yttria-Stabilized Zirconia (3YSZ, 8YSZ) for use in fuel cells, TBCs, and oxygen sensors.
Can zirconia be used for thermal barrier coatings?
Absolutely. Zirconia ceramics, especially YSZ, are standard materials in EB-PVD and plasma spray coatings for turbine blades, combustion chambers, and exhaust systems, thanks to their low thermal conductivity and phase stability.
