Zirconia Ceramics


Zirconia, or zirconium dioxide, is a white crystalline oxide of zirconium that is often stabilized with other oxides. At room temperature, zirconia possesses a monoclinic crystal structure, but at higher temperatures this transitions to a tetragonal structure. Upon cooling, these structures endure large stresses, which often cause cracking. Since zirconia is most useful in its stabilized form, oxides such as magnesia (magnesium oxide) or yttria (yttrium oxide) are blended to stabilize this structural transformation. The resulting material offers superior thermal, electrical, and mechanical properties, including high toughness, high hardness, and high resistance to thermal shock.

We offer zirconia in three formulations, including partially and fully stabilized varieties, to accommodate a wide variety of industrial applications. Zirconia is a strong refractory material with many applications, including oxygen sensors, fuel cell stack insulation, fuel cell membranes, chemical processing and refining applications, and refractory applications.
