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.
