Zirconia Ceramic Materials Precision Ceramics USA
Yttria Partially Stabilized Zirconia (Y-PSZ) is doped with Yttrium oxide (Y2O3) as a stabilizing agent which stresses the internal grain structure and makes the material stronger by changing it from a monoclinic to tetragonal phase. It is a fine grain material that has one of highest flexural strength among all ceramic materials. CUMI manufactures Fused Calcia Stabilzed Zirconia material for use in the manufacture of slide gate refractories used in the continuous casting of steel. A mixture of high quality zirconia and lime is fused at a temperature greater than 2400oC to create a partially stabilized zirconia product.

Preparation of Yttria-Stabilized Zirconia Hollow Sphere
Yttria-stabilized zirconia (YSZ) hollow sphere (HS) powder is a novel potential feedstock material for the plasma spraying of next generation advanced thermal barrier coatings with low thermal conductivity and high sintering resistibility. Most widely used commercial zirconia powders are composed of porous particles 10-105 μm and 45-75 μm in size. Furthermore these powders are mixtures of tetragonal cubic and monoclinic modifications which indicate the heterogeneous distribution of the stabilizing yttria dopant in finished powder not suitable for Solid oxide fuel cell applications.

Towards a generic method for inorganic porous hollow
A versatile method is presented for the preparation of porous inorganic hollow fibers with small tunable radial dimensions down to ∼250 μm outer diameter. The approach allows fabrication of thin hollow fibers of various materials as is demonstrated for alumina nickel silicon carbide stainless steel and yttria stabilized zirconia. Subsequently various metal ferrite samples (NiFe 2 O 4 MgFe 2 O 4 CoFe 2 O 4 and MnFe 2 O 4) in yttria stabilized zirconia (8YSZ) were synthesized via coprecipitation and tested to determine the most promising metal ferrite combination.
