Because of its superior mechanical properties and smooth appearance, zirconia materials are now widely used in mechanical parts, electronic parts and cutting tools, to watch cases and manufacturing of optical fiber connector ferrules. Other notable applications are grinding media, and precision components.
Our factory produces yttria stabilized zirconium oxide by wet-chemical process which ensures a uniform dispersion of yttria. Our strict quality control system ensures consistent quality from batch to batch, a critical point in today's final product manufacturing. Our Zirconium Powder is known for its consistent stability andquality. Our product series includemonoclinal zirconium oxide powder and zirconium oxide powder with yttria stabilized. and suitable for dry press, CIP mould, injection mould, tape casting forming and so on.
Zirconia Power Type
◆SG0-TZP monoclinic powder :
Features:
● white solid powder with non-poisonous and non-taste.
● enough stabilization to alkali and many kinds of acid liquor (except for H2SO4,HF and H3PO4). ● 100% monoclinic.
● produced with advanced coprecipitation
● high purity and Ultrafine powder with size of 0.3 ~ 0.8 μ m
● applied in mixed of electronic components material, ceramic material and padding fired.
◆SG3-TZP Powder
Which is particularly stabilized with 3mol% yttria, is the standard grade which can be used in various forming methods to achieve a dense sintered body with well-distributed crystalline grains.
◆SG3S-TZP Powder
This grade of powder have a smaller surface area which contributes to a better flowability of the compound(slurry) in injection molding tape casting. For the production of large parts by mechanical press or ICP, this grad is recommended.
◆SG8-TZP Powder
Fully stabilized zirconia powder contains 8 mol% yttria. The sintered body is pure cubic zirconia and has high ionic conductivity. Therefore, it is used for the manufacture of sensors and solid oxide fuel cells.
◆Spray Dried Powder
Partially and fully stabilized zirconia powder are provided. Size of powder is between 30~70μm.
