Starrbide

Starrbide crucibles are carbon-bonded silicon carbide crucibles, which are characterized by excellent thermal conductivity and high chemical erosion resistance. Due to their carbon content, SiC crucibles have excellent stability at high temperatures and are therefore particularly suitable for processes where the temperature is changing frequently and where high heating rates are utilized.

Applications

Starrbide crucibles are particularly suitable for processes with frequently changing temperatures and high heating rates. Starrbide crucibles can be used for the holding of all non-ferrous alloys. They have a very high mechanical strength and a high refractoriness, making them especially suitable for melting heavy metal alloys. Additionally, they are resistant to chemical attack by fluxes. Starrbide crucibles are suitable for electric resistance heated and fuel-fired and induction furnaces. They perform well under difficult operating conditions.

As a consequence of user-related innovative developments, optimised Starrbide variants are available.

Starrbide HT / VO crucibles are particularly appropriate for melting copper and bronze alloys in furnaces with high power and high heating rates. 

Starrbide U IND crucibles are suitable for medium frequency induction furnaces for melting and holding. They perform well under difficult operating conditions.
