Mullite

Axim’s mullite offers many of the same properties as alumina, with a slightly improved thermal shock properties.
Mullite is a good, low cost refractory material with a nominal composition of 3Al2O3•2SiO2. The raw materials are easily obtainable and are reasonably priced. Axim’s mullite has excellent high temperature properties with improved thermal shock and thermal stress owing to the low thermal expansion, good strength and interlocking grain structure.

Key properties:
  • Excellent thermal shock and stress resistance
  • Low thermal conductivity
  • Excellent strength
  • Wear resistant
  • Usable to high temperatures

Applications:
  • Protection tubes
  • Furnace liners
  • Electrical insulators
