Refractory Metal Oxides

Vanadium oxide

Vanadium oxide is a powder that is available in various purities and particle sizes. We can also produce it with application-specific characteristics upon request.

• Vanadium pentoxide (V₂O₅)
• Vanadium trioxide (V₂O₃)

 

Niobium oxide Nb₂O₅

Titanium oxide TiO₂

Hafnium oxide HfO₂

Molybdenum oxide MoO₂^:  Roasted Molybdenum Concentrate

Tungsten oxide WoO₃^: blue WO_2.97, yellow WO₃

Tantalum oxide Ta₂O₅

 

 

 

 

Zirconium oxide ZrO2

Zirconium oxide ZrO2 occurs in various crystal modifications that have a significant impact on the mechanical characteristics. Pure zirconia (not stabilized) is available as a white powder in various purities:
• ZrO2 min. 99.50 %
• ZrO2 min. 99.95 %

Doped zirconium oxides
Zirconium oxides can be doped with cerium (Ce), scandium (Sc), yttrium (Y) and other elements. We can offer both chemically precipitated and fused material.
 
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.

• 3 YSZ 3.00 Mol% Yttria
• 7.5 YSZ  7.50 Mol% Yttria
• 8 YSZ  8.00 Mol% Yttria
 
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.
