PYROLIT – Cordierit
PYROLIT C 410 is a dense cordierite with high mechanical stability. It is used above all in applications that do not tolerate any pores in the material (humidity).
PYROLIT C 520 is a fine porous material and very resistant to changes in temperature due to the increased proportion of cordierite. It is the standard material for many applications and can be processed very cost-effectively due to the high volume production output.
Because of the increased aluminium oxide content, PYROLIT C 530 has an extremely good thermal shock resistance and a high compression strength. It displays the highest heat resistance of all cordierite materials of approx. 1300°C. Through the addition of mullite, the application temperature can be increased up to 1600 °C (customised products).
Production & properties
Typical moulding procedures are dry pressing, wet pressing and extrusion. Almost every geometric shape is possible.
As a speciality, we also offer you large components, such as large ceramic tubes with threads, grooves or notches, produced with manufacturing procedures and processing techniques developed in-house.
Applications
Their very good electrical properties make PYROLIT materials ideal for application in electrical heating technology.
Approved products include heating element supports, spark protection walls and insulators in the area of high and rapidly changing temperatures, welding back-ups, sensor housings for thermocouples, to measure temperature during steel production and mould for foundries. This material is also ideal for ceramic tubes, multi-hole tubes or spiral pipes, for example for furnace construction, hot air fans or as spark killers.
