Zirconia ZrO₂
ZrO₂ occurs in various crystal modifications that have a significant impact on mechanical characteristics. Certain crystal modifications must be stabilized using oxides (e.g. Y₂O₃, CeO₂, MgO) for manufacturing densely sintered products.
Pure zirconia (not stabilized) is available as a white powder in various purities:
• ZrO₂ min. 99.50 %
• ZrO₂ min. 99.95 %

 

Yttria stabilized zirconia YSZ
YSZ is one of the most popular raw materials for manufacturing components that are subject to high mechanical loading. This white to yellowish powder containing 3 – 8 mol.% YSZ is produced using chemical precipitation or melting (high-density powder). The particle size varies between 0.5 µm and 1 mm.

 

Ceria stabilized zirconia CeSZ
CeSZ, like YSZ, exhibits excellent fracture toughness and is therefore ideal for structural ceramic components. Standard products contain 18% ceria (CeO₂) by weight. The particle size ranges from <1 µm to 1 mm. Our production technology uses chemical precipitation or melting to generate CeSZ.
