      Zirconia Stabilized with Yttria Crucibles

      Goodfellow can now offer Yttria stabilized Zirconia crucibles. These crucibles are ideal for specialist applications, and Yttria stabilized Zirconia offers several benefits.

      • A melting point 500 degrees C higher than Alumina.
      • Low thermal conductivity. These crucibles can be used in areas of extreme mechanical abrasion and thermal shock.
      • Fracture toughness x 2 higher than Alumina.
      • High quality surface finish.
      • High resistance to chemical attack.
