Nozzles and Slide Valves for Flow Control

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