Zirconia (YSZ) Rod

Yttria Stabilized Zirconia (YSZ or YTZP) represents a class of advanced ceramic materials that stand at the forefront of sintered zirconia ceramics. Renowned for its exceptional stability, YSZ is typically composed of 94.7% ZrO2 and 5.2% Y2O3 by weight, or 97% ZrO2 and 3% Y2O3 by molar percentage. This subtle infusion of yttria into zirconia crystal structure yields a ceramic that far exceeds the capabilities of common alumina rods in terms of temperature resilience.
Capable of enduring extreme temperatures up to 1900°C, YSZ rods boast remarkable resistance to both thermal shock and wear. This makes them highly suitable for applications where high durability and prolonged exposure to elevated temperatures are crucial. YSZ's resistance to corrosion also extends to a broad spectrum of corrosive chemicals, underscoring its versatility in harsh environments.
Moreover, the low thermal and electrical conductivity of YSZ ceramics makes them ideal for applications that demand excellent electrical and thermal insulation. Zirconia crucibles, shaped from this material, are particularly favored in processes where controlled insulation is paramount. All these attributes converge to establish Yttria Stabilized Zirconia as a material of choice for industries requiring robust performance under challenging conditions.
However, unlike boron nitride, Zirconia rod is not recommended to be used as a raw material for further machining work, due to the high hardness and wearing resistance.
