CRUCIBLES
Freedom of choice.
1 Gray
ceramic for most gold and silver as well as
stainless steel alloys.
2
White ceramic for high deox silver and gold alloys.
3 Graphite
for high copper alloys.
MEMCO invented the susceptor/crucible concept and began manufacturing
it in 1981. This allowed the use of crucibles other than the common
graphite. The advantages of the unique ceramic crucibles are:
• Completely inert to prevent chemical interaction and
contamination of the melt
• Durable ceramic crucible has a much longer life than graphite
as it doesn't oxidize, leak, or crumble and fall into the flask opening.
• Bottom pour arrangement allows the clean metal to enter the
mold first while any residue is held until the end.
• Precision orifice controls pour rate to minimize turbulence
effects on the casting. The precision pour hole design does not
enlarge or change shape with age or usage.
• Ceramic crucibles are pressed under very high pressure into
metal molds giving very dense, dimensionally accurate parts. These
crucibles are guaranteed to provide maximum heat transfer from the
susceptor.
