Zirconia Crucibles – For Air and Induction Melting Applications
Dyson Technical Ceramics™ Isostatically Pressed Zirconia Crucibles offer resistance to high temperatures, while maintaining excellent erosion resistance. This allows the caster to operate for longer, at higher temperatures, making Zirconia the preferred choice of crucible material for applications such as:
- Platinum/Platinum group metals
- Nickel based super alloys
- Cobalt based super alloys
- Sputter material for hard disk drives
The use of high purity raw materials and Dyson’s dedication to quality ensures our products perform well consistently. In addition to this Dyson’s efficient manufacturing techniques make sure our clients receive what they need, when needed.
In order to provide quality products Dyson™ delivers materials of the highest quality to the market, competitively priced and backed by the expertise of application knowledge and the resources of the Research & Development Laboratory in Sheffield.
Product development is both proactive and reactive in that new materials and technologies are constantly reviewed and where appropriate incorporated into the manufacturing facilities. Selection of materials is made by reference to an extensive application database, which, in conjunction with close liaison with end users, provides materials offering optimum performance in terms of cost and operation.
Dyson Technical Ceramics™ manufactures a wide range of crucibles based upon stabilised Zirconia. The properties of the finished product are determined by both the manufacturing method and the choice of the stabilising media. Oxides of Calcia, Magnesia and Yttria are utilised as stabilising agents and each product is characterised by differing thermal properties.

Dyson's Crucible Sizes
Below is a list of common crucible sizes. Please note that the sizes are accurate for our "ISO Zirconia M" composition. Crucible sizes will vary depending on composition choice, due to shrinkage during sintering. While all zirconia crucibles are similar in size, Alumina crucible may be up to 3.5% larger than the dimensions quoted below.
