YSZ1871 Yttrium Oxide Stabilised Zirconium Dioxide Micropowder (YTZP/YSZ Micropowder)

Description of Yttrium Oxide-Stabilised Zirconium Dioxide Micropowder

Yttrium oxide‐stabilised zirconium dioxide, also known as yttrium oxide‐hardened zirconium dioxide polycrystal (Y‑TZP), is a high‐strength, fine‐grained ceramic material. It exhibits chemical inertness and corrosion resistance at temperatures up to 2 200℃, which is considerably higher than the melting point of earthenware. The zirconium dioxide is stabilised in the cubic crystal structure to prevent crack formation and mechanical weakening during heating and cooling. In addition to its fire resistance, it delivers low thermal conductivity and becomes electrically conductive above 800℃. Furthermore, oxygen ions are mobile within the crystal structure at temperatures above 600℃.

FAQs about Yttrium Oxide-Stabilised Zirconium Dioxide Micropowder

Q1: What are the principal properties of YSZ micropowder?

A: The primary properties include high toughness, high fracture strength, good ionic conductivity, thermal stability, wear resistance and chemical inertness.

Q2: How is YSZ micropowder produced?

A: YSZ micropowder is produced by doping zirconium dioxide with yttrium oxide. Consequently, the powders are mixed, pressed into the desired shape and then sintered at high temperatures to obtain a dense and stable ceramic.

Q3: What are the available particle size ranges for YSZ micropowder?

A: YSZ micropowder typically has particle sizes ranging from a few micrometres to several tens of micrometres, depending on the synthesis method and application requirements.
