China Factory Wholesale High Quality Zirconia Powder Yttria
Stabilized Ultrafine Zirconia Powder
Zirconia has the characteristics of high hardness, high-temperature
resistance, chemical corrosion resistance, wear-resistance, small
thermal conductivity, strong thermal shock resistance, good
chemical stability, outstanding composite material, etc. The
properties of the material can be improved by combining nanometer
zirconia with alumina and silicon oxide. Nano zirconia is not only
used in structural ceramics and functional ceramics. Nano zirconia
doped with different elements conductive properties, used in solid
battery electrode manufacturing.
Features of High Quality Zirconia Powder:
1. Small particle diameter, narrow distribution range, activity,
stable.
2. Excellent liquidity and compactness, easy to mold and sinter.
3. BET and particle size of airflow or granulation one can be
controlled on customers's request.
Product Applications of High Quality Zirconia Powder
In recent years, Zirconia Ceramics are increasingly used for
biomedical applications . Zirconia is used as a biomaterial. It has
advantages over other ceramics because of its high mechanical
strength and fracture toughness. Biomaterials have been proposed as
artificial bone fillers for repairing bone defects. Zirconia also
finds other clinical applications such as: arthroplasty, dental
crowns.
Though zirconia and Yttria stabilized Zirconia have orthopedic
applications such as hip and knee prostheses, hip joint heads,
temporary supports, tibial plates, dental crowns, not much
literature reports are available on the studies of this oxide
ceramics as drug carriers. etc. Zirconia toughened alumina ceramic
foams can be used in potential bone graft applications. Thin films
of ZrO2 (Zirconia) have beneficial ceramics properties that offers
various possibilities for
Technological application such as optical coating, thermal barrier,
catalysis or catalytic supports.
Yttria-stabilized zirconia thin films by dip-coating for IT-SOFC
application . Solid oxide fuel cell (SOFC) ceria/yttria stabilized
zirconia electrolytes for solid oxide fuel cell applications .
Zirconia is used as air-fuel ratio sensors for Progress in
Synthesis and Applications of Zirconia 26 automotive applications .
To combine the mechanical properties of a high strength inert
ceramic with the specific properties of bioactive glasses,
composite materials based on high-density zirconia substrates
coated by bioactive glasses are reported to be used . Zirconia
ceramics can be used for functional as well as structural
applications.
