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

Evaporation Baskets promote line-of-sight coating.

August 14, 2007

Available in 6 sizes with wire diameters from .020-.050 in., Alumina Coated Evaporation Baskets are internally heated crucibles that permit vacuum evaporation of several metals simultaneously, and maintain molten metals evaporants as induction propelled spinning ball within cavity. Units completely evaporate most materials such as gold, nickel, palladium, and silver without loss to chamber. Inside depths range from .225-.975 in. and top IDs range from .150-.900 in. Read More

Material Handling & Storage, Materials & Material Processing

Crucibles are suited for melting high purity metals.

May 26, 2006

VX Crucibles operate under severe conditions including temperatures up to 1,450ºC and extreme thermal shock conditions. They offer thermal expansion of 6 x 10<sup>-7</sup>/°C at 1,000°C, low specific gravity, low thermal conductivity, and high electrical resistivity. Available in various shapes and sizes, products are suited for brazing, sintering, melting, and heat treating applications in dental, jewelry making, and metal brazing industries. Read More

Materials & Material Processing

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
