New Super-Heat Magnesium Oxide Ceramics Now Available

Valley Cottage, NY – Aremco's Super-Heat™ 502-676 Magnesium Oxide (MgO) Ceramic Crucibles are now available for use in the processing of ultra high temperature refractory metals, slags and superconductor compounds to 4000°F.


Aremco's Super-Heat 502-676 MgO ceramic is a full-fired, 99% pure material used in applications to 4000°F (2200°C). Super-Heat 502-676 MgO is a high density, fine grain microstructure with an open porosity of less than 1% and an average density of 3.45 grams/cc or 96% of theoretical. This ceramic is an ideal alternative to alumina because it exhibits better chemical resistance and is inert to metals, slags and superconductor compounds.

Typical applications for Super-Heat 502-676 MgO include the processing of:

• Nickel-Base Super Alloys

• Plutonium & Uranium Compounds

• Superconductor Materials

• Piezoelectric Compounds

• Beta-Alumina

Super-Heat 502-676 MgO Crucibles are now available in both stock and custom shapes up to 7" diameter x 12" length with a wall thickness of 0.2" maximum.

Please contact Aremco's Technical Sales Department for a listing of standard crucibles or for more information about this advanced product.
