New Super-Heat Magnesium Oxide Ceramics Now Available



Valley Cottage, NY - February 4, 2005

SUMMARY

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

FEATURES

Aremco's Super-Heat tm 676 MgO ceramic is a full-fired, 99% pure material used in applications to 4000 °F (2200 °C). Super-Heat(TM) 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(TM) 676 MgO include:

Metal Alloy Processing such as nickel base super-alloys and plutonium and uranium systems.

Superconductor Processing - resists attack and is non-contaminating to 1-2-3 materials.

Piezoelectric Materials Processing - resists lead-based materials.

Beta-Alumina Processing - resists sodium attack.

Super-Heat(TM) 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.

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