The Zirconia Toughened Alumina (ZTA) Cylindrical Crucible is an advanced composite ceramic renowned for its exceptional mechanical properties. Crafted by introducing Zirconia into the primary Alumina matrix prior to sintering, it seamlessly combines the strengths of both materials, providing unparalleled mechanical strength and resistance to abrasion. Zirconia Toughened Alumina (ZTA) surpasses typical alumina ceramics in strength and toughness, offering heightened thermal shock resistance at a more economical price point than pure zirconia. Furthermore, ZTA crucibles showcase superior surface finish compared to Alumina, making them an ideal choice for applications requiring bio-compatibility and analytical precision.
