Yttria Stabilized Zirconia (YSZ) is a type of zirconium dioxide (ZrO2) that is stabilized with yttrium oxide (Y2O3). This stabilization process involves doping zirconia with yttria to maintain the cubic phase of zirconia at room temperature. YSZ is known for its high ionic conductivity, mechanical strength, and thermal stability, making it highly suitable for various applications in Nanotechnology.
