YSZ
Zirconia(ZrO2) single crystal wafer is one of the most early high temperature superconducting substrate. Because Zirconia needs to be dopped with yttrium to stable its structure, normally the dopped yttrium dopped Zirconia(YSZ) single crystal is used. The mechanical stability and chemical stability of YSZ is excellent, and it has relatively lower price, which is especially applicable in making positive film.CasCrysTech (CCT) provides high quality Zirconia(ZrO2) crystals upon request from customers.
