What is Zirconia Toughened Alumina?
Zirconia Toughened Alumina is a ceramic wear-protection product made from high-purity yttria-stabilized zirconia (YSZ / Y-TZP), used to protect equipment from abrasive and impact wear. The yttria-stabilized zirconia body gives density ≈ 6.0 g/cm³, hardness ≈ 1200 HV and exceptional fracture toughness, resisting chipping better than alumina. In mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants, they extend equipment life and cut maintenance.
What is Zirconia Toughened Alumina used for?
They protect process equipment from wear in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
What material and properties make Zirconia Toughened Alumina effective?
The yttria-stabilized zirconia body gives density ≈ 6.0 g/cm³, hardness ≈ 1200 HV and exceptional fracture toughness, resisting chipping better than alumina. These properties let Zirconia Toughened Alumina outlast steel and rubber in abrasive service.
Why choose Zirconia Toughened Alumina over steel or rubber alternatives?
Zirconia Toughened Alumina beat steel or rubber on abrasive duties: steel erodes in months and can contaminate product, while rubber gouges under lump impact. Zirconia Toughened Alumina hold dimension, cut downtime and typically last 5–10× longer in mining, cement, steel, power-plant ash handling, chemical processing and lithium-battery material plants.
How do I select and specify Zirconia Toughened Alumina?
Tell FIRSTAR your equipment, material and wear mode; we specify grade, size and backing to match.
What maintenance do Zirconia Toughened Alumina need?
Little maintenance is needed beyond periodic inspection; because they wear slowly, planned replacement during shutdowns is usually enough. FIRSTAR can advise an inspection schedule.
