Aluminium Titanate crucibles(Al2TiO5 crucibles)

Product Information

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. 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. aluminum titanate has outstanding properties that make it ideally suited for applications involving molten aluminum, including complete resistance to wetting by aluminum alloys, total gas impermeability, and a very low thermal expansion coefficient. This material offers a longer service life and higher reliability when compared to cast iron, calcium silicate or fused silica components. All riser/stalk tubes are 100% leak-down tested, and parts are available with gasketing and ceramic foam filters to provide complete assemblies.
