Graphite & Ceramic Melting Crucibles

RDO offers an extensive line of graphite & ceramic melting crucibles for all your melting needs.   We are also able to supply custom size crucibles upon request.

The graphite crucibles are designed to melt metals such as gold, silver, copper, aluminum and platinum and withstand temperatures up to 1600°C.  These graphite crucibles are ideal for our LC series induction melting systems. The Silicon Carbide crucibles (SIC) are used when melting with our larger induction melting systems and do not oxidize and break down as quickly as graphite.  These types of crucibles are also used in some of our smaller furnaces in order to attain higher purity melts without the potential for graphite contamination.

Our large ceramic crucibles are used with our S series induction melting systems along with gas fired systems.  We also have ceramic crucibles for the melting and casting of Platinum, Palladium, Steel and Titanium in our EasyCast, Supercast and CS series casting machines.

Once you have found the crucible you are interested in, please submit a quote request or ask a question using one of our forms.
