Zirconia crucible products and other ceramic materials

Alumina crucibles and Zirconia other options

We stock and supply high purity  zirconia and alumina crucibles in various shapes (both flat and cylindrical bottom, conical or straight wall) as well as other labware items such as ignition dishes, laboratory boats, basins and lids. We have a wide range of standard sizes and are also able to supply custom size and shaped products.

Our dense crucible range extends in volume capacity from 0.5 ccm to 1700 ccm. Larger sizes are also possible.

To suit the application requirements, we are also able to supply and deliver labware in a range of different materials including:

  • Dense Yttria or calcium stabilised zirconia
  • Zircon
  • Mullite
  • Yttria
  • Hafnia
  • Fused Silica
  • Porcelain
  • Quartz

With the exception of the Quartz materials, these materials are typically cast or pressed, dried and fired. Quartz products are typically hand shaped at temperature. Quartz products can be shaped into complex forms in both low and medium volumes so are ideal where custom product is required.

We also provide refractory grade porous alumina, mullite and zirconia crucible options for superalloys and other metals melting, precious and semi-precious melting, glass melting, etc.

Our standard range of refractory products includes isostatically pressed or rammed crucibles and a range of speciality high alumina refractory grade crucibles with high performance characteristics.

Our wide range of ceramic materials both standard and non-standard will meet your application requirements. Please discuss with us what it is you need.
