Oxide Ceramics – Aluminum Titanate (Al2TiO5)

A Material with Excellent Thermal Shock Resistance

The special feature of aluminum titanate (Al2TiO5) is its excellent thermal shock resistance. Components made of this material can withstand even the most abrupt temperature changes of several hundred degrees without damage, although they have low strength.

Worth knowing:

Properties of Aluminum Titanate (Al2TiO5)

  • Excellent thermal shock resistance
    (0 – 1,000°C)
  • Very low thermal expansion (<1x10-6K-1 between 20 and 600°C)
  • High thermal insulation (1.5 W/mK)
  • Low Young’s modulus (17 to 20 GPa)
  • Good chemical resistance
  • Poor wettability with molten metals

Oxidkeramik – Aluminiumtitanat

The good thermal shock resistance is a result of the very low thermal expansion and a certain amount of porosity in the microstructure. This ceramic material’s poor wettability with molten metals also makes it ideal for use in foundry technology and metallurgical melting.
