Pyrolite

In Pyrolite we offer a variety of dense and porous ceramic materials, which show a very good thermal shock resistance at high thermal and electrical insulation.

Material

Pyrolite is our trade name for a range of cordiertie materials C410, C511 and C520 according to IEC 672. They are Magnesia / Aluminia / Silicate materials with addition of mullite, corundum and silicon carbides.

Characteristics for these materials are:
- Good thermal shock resistance
- Good electrical insulation
- Low thermal expansion
- Good mechanical strength
- Corrosion resistance
- An inert material

Pyrolite C 410 is a dense material having the highest mechanical strength together with excellent thermal shock resistance.

Pyrolite C 511 is a fine grained porous material, suitable for aggressive solutions and resistant to atmospheric conditions.

Pyrolite C 520 is a fine grained porous material with a better thermal shock resistance than C410 and C511

Pyrolite C 530 is a fine grained porous material having the best thermal shock resistance and electrical resistivity per °C. It also has the same higher flexural strength of C520.

Production

Typical production processes are dry and semi-wet pressing and extrusion.

Spread-sheet Pyrolite

Applications

These materials have many applications throughout heating technology:

- Fuse tubes
- Thermocouples
- Weld back ups
- Spark killers
- Insulation with thermal shock
- Crucibles
- Foundry products
- Heating element supports

Inquiries

To enable us to forward quotations, please send us a drawing of the part your require indicating the critical areas, tolerances and quantities. If it is a new component indicate the application, which will enable us to suggest the best material for your part.

We are willing to discuss any application or new product with you and we will maintain total confidentiality. Besides ceramic we also manufacture plastic parts and if required we can mould your ceramic into plastic.
