YSZ Substrate

Yttrium-doped zirconia (YSZ) single crystal substrate is one of the earliest materials used in high temperature superconducting thin films. Generally used zirconia needs to be doped with yttrium as a stabilizer, the common concentration of 13 mol%, YSZ is characterized by good mechanical and chemical stability and low cost, it has been widely used in ceramics, refractories, machinery, electronics, optics, aerospace, biology, chemistry and so on.

OST Photonics offers high quality YSZ substrates for researchers and industries. Crystal orientation, size and thickness can be customized according to your requirements.
