Magnesium Oxide Ceramics withstand temperatures up to 4,000°F.

May 7, 2013

Super-Heat ™ 502-676 Magnesium Oxide Ceramic Crucibles are manufactured with full-fired, 99% pure material used in processing high-temperature refractory metals, slags, and superconductor compounds. Products feature high-density, fine-grain microstructure with open porosity of less than 1% and average density of 3.45 g/cc. They are available in stock and custom shapes with up to 7 in. dia, 12 in. length, and wall thickness of 0.2 in. maximum. Read More

Ceramic Crucibles hold metals up to 4000 deg F.

February 14, 2002

Super-Heat(TM) 676-Series Magnesium Oxide crucibles can be used for ultra-high temperature processing of metals, slags, and superconductor compounds. MgO ceramic is full-fired, 99% pure material with high density (3.45 g/cc) fine-grain microstructure. It offers alternative to alumina because it exhibits better chemical resistance and is inert. Crucibles are available in both shapes up to 7 in. dia, 12 in. long, and with wall thickness of 0.2 in. Read More
