Mullite (Pythagoras)

We offer a range of mullite materials marketed under the Pythagoras™ name for our Haldenwanger^® range of products.

Our Pythagoras™ material is the most economical mullite material for kiln components. This material has good thermal shock resistance and good mechanical strength for kilns working under normal conditions up to 1400°C. It features very good chemical resistance against gases free of fluorine and is very economical as it is used as impervious protection sheaths and insulators for temperature measurement.

Pythagoras™ 1800 Z

An impervious, mullite high performance material.

• Refractoriness up to 1600°C
• Very high thermal shock resistance
• High mechanical strength
• High electrical insulation even at high temperatures
• Evaporation extremely low, therefore no contamination of kiln atmosphere; no reaction with heating element
• Most suitable material for radiant heating tubes
• Kiln tubes made of Pythagoras™ 1800 Z can be very thin-walled
