Vitreous Carbon Rod

Vitreous Carbon

Often referred to as glassy carbon, this fragile, black glass has a closed micro-porosity, is impervious to gas and has excellent thermal shock resistance.
CL10Z Zirconia Classic Crucible 14ml

Zirconia

Superior refractoriness, excellent machinability, and useful ionic conductivity properties compared to alumina.
Round Shallow and EBEAM Crucibles - 116e

ZTA

Tough ceramic composite for extreme mechanical and thermal conditions.
If the material you require isn’t listed please use the button at the bottom of the page to contact us for a bespoke solution. There is a wide variation of ceramic materials available and further variation within the different materials (for example porous and non-porous alumina). Each of the ceramic materials have different properties with regard to porosity, thermal conductivity, max temperatures, thermal shock resistances and more, they also have different associated costs, so where porcelain is an effective low budget ceramic material that is often purchased in bulk, vitreous carbon is an expensive material that is often used for custom designs or smaller batch production.

Our main materials are Alumina (Aluminium Oxide) and Zirconia (Zirconium Dioxide), you will find the bulk of our products are made from these materials as they are dense, durable, high purity ceramics with good resistance to thermal shock, can be used at extreme temperatures up to 1800°c and 2200°c respectively.

Please consult our full list of ceramic products to find the shape you require for your processes, or contact us for a quote on a custom design.
