Introduction Yttrium stabilized zirconia substrate YSZ
Yttrium Stabilized Zirconia -YSZ substrate is one of the earliest materials used in high-temperature superconducting thin films.
Usually using the zirconium oxide necessary to incorporate yttria as a stabilizer. Common doping concentration in 13 mol%, YSZ has a good mechanical and chemical stability, low cost. It has been named Yttria stabilized zirconia.
Because of zirconium oxide material with high hardness, high strength, high toughness, high wear resistance and excellent chemical resistance and many physical and chemical properties, zirconium oxide has been widely applied in various fields: ceramics, refractories, machinery, electronics, optics, aerospace, biology, chemistryand so on.
Characteristics Yttrium stabilized zirconia substrate YSZ
- refractory products
- thermal barrier coating in gas turbines
- electroceramic elements
- jewelry.
- non-metallic knife blades
- alignment sleeve for optical fiber connector ferrules.[12]
