Riser Tubes

Conveying of molton aluminum
Al2TiO5 und Si3N4 


  • excellent thermal shock and corrosion resistance
  • very low wettability of non ferrous metal melts
  • increased productivity
  • reduction of machine down time

H.C. Starck produces riser tubes for dosing and conveying of molten aluminum. These parts can be made from our high tech ceramics StarCeram® AT or StarCeram® N. Both materials are characterised by excellent thermal shock and corrosion resistance as well as  very low wettability by non ferrous metal melts. Besides an extremely high mechanical strength, Silicon Nitride has also very good thermal conductivity. In contrast, Aluminum Titanate shows excellent insulating properties.

Available length: Max. 1,550 mm.
