Oxide Powder

Zirconium IV Oxide -Yttria Stabilized: Monoclinic zirconium oxide can be restricted in its applications due to the phase transformations it undergoes during heating. These phase transformations lead to changes in volume resulting in structural cracking and failure. These phase alterations can be controlled by the addition of dopants known as stabilizers. Once stabilized, zirconia can be used in applications running at temperatures in excess of 2200◦C. Nanoshel offers a range of stabilized fused and co-precipitated zirconia powders.

Zirconium IV Oxide -Yttria Stabilized: Stabilized Zirconium oxide is the very low thermal conductivity and high strength. In addition, some types of zirconium oxide ceramics can conduct oxygen ions. Components made from this material are significantly more expensive than components made of alumina ceramics. Zirconium oxide are used, among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.

Zirconium IV Oxide -Yttria Stabilized: Zirconia (zirconium oxide) is a crystalline oxide which exists in three phases with different crystal structures depending on the temperature - monoclinic, tetragonal, and cubic. There is a significant volume change associated with the monoclinic-tetragonal transition, which can cause problems when processing the materials.

Zirconium IV Oxide -Yttria Stabilized: Fused zirconium oxide can be stabilized during the fusion process by the addition of stabilizers such as yttria, magnesia and calcia. After fusion the material is crushed and milled to different particle sizes. Zircomet Limited supplies a range of YSZ, MgSZ and CaSZ powders with particle size distributions produced for specific applications or to customer specification.

Zirconium IV Oxide -Yttria Stabilized: A fully stabilized zirconia has a structure which is a cubic solid solution which has no phase transformation from room temperature up to 2500 degrees C. Fully stabilized zirconia is a very good ion conducting ceramic and is used in applications such as oxygen sensors and solid oxide fuel cells.
