YSZ1870 Yttrium oxide-stabilised zirconium dioxide nanopowder (YTZP/YSZ nanopowder)

Yttrium Oxide Stabilised Zirconium Dioxide Nanopowder Description

Yttrium oxide stabilised zirconium dioxide, also known as yttrium oxide‐hardened zirconium dioxide polycrystal (Y-TZP), is a high-strength, fine-grained ceramic material. YSZ demonstrates chemical inertness and corrosion resistance at temperatures up to 2200℃, which exceeds the melting point of clay. Zirconium dioxide is stabilised in the cubic crystal structure to prevent crack formation and mechanical weakening during heating and cooling. In addition, these materials exhibit low thermal conductivity and become electrically conductive above 800℃. Furthermore, they permit oxygen ions to move freely through the crystal structure above 600℃.

FAQs on Yttrium Oxide Stabilised Zirconium Dioxide Nanopowder

Q1: How is YSZ nanopowder produced?

A: YSZ nanopowder is produced using methods such as the Sol-Gel process, hydrothermal synthesis, co-precipitation and spray pyrolysis. These methods allow precise control of particle size, composition and purity.

Q2: How does the yttrium oxide content affect the properties of YSZ nanopowder?

A: The yttrium oxide content influences the phase composition and stabilisation of zirconium dioxide. Typically, 3–8 mol-% yttrium oxide is employed to stabilise the tetragonal and cubic phases, thereby ensuring fracture resistance and ion conductivity.

Q3: How is the quality of YSZ nanopowder verified?

A: Quality is verified using techniques such as X-ray diffraction (XRD) for phase analysis, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) for investigating particle size and morphology, and thermal analysis for stability and conductivity measurements.
