Molybdenum-hafnium carbide (MHC) is highly temperature-resistant, has a high level of thermal conductivity, a low coefficient of thermal expansion and a high recrystallization temperature. MHC retains its shape even when used at temperatures of up to 1 550 °C. At temperatures up to 800 °C, MHC is suitable for use in die inserts. At higher temperatures, the producer recommends using MHC for full dies. The benefits to you for a long service life: — Optimum nondeformability and dimensional stability — Low tendency to crack in the case of edged profiles — High thermal stability — High thermal conductivity — Low thermal expansion — Good hot ductility — Very high recrystallization temperature Plansee supplies MHC components in disc form with or without drilled start hole.

Metallic hot zones are made for very high temperatures between 1000 °C (1 832°F) and 2 800 °C (5 072 °F). As a specialist in refractory metals Plansee delivers molybdenum and tungsten hot zones with an excellent form stability and lifetime. Plansee designs and produces hot zones for various types of furnaces (vacuum, protective gas atmosphere, HIP etc) and thermal processes such as sintering, brazing or annealing. Hot zones consist of countless individual parts such as heating elements, shield packs and hearth assemblies and charge carriers. You can find all of these components at Plansee. - Hot zones made from molybdenum, tungsten, tantalum, niobium and their alloys - Full metal or hybrid hot zones with graphite or ceramic fiber insulation - From very small (a few cm³) through to very large (several m³) hot zones - For temperatures of between 1000°C (1832°F) and 2800°C (5072°F) - Tailor-made design: round, rectangular, vertical, horizontal or special geometries

Molybdenum and tungsten crucibles from Plansee are the perfect vessels for melting and solidifying the single crystal. The formed crucibles have particularly thin walls combined with excellent creep resistance. The outstanding purity of the crucibles prevents any contamination of the single crystal. Even the most aggressive sapphire melts cannot do any harm. Plansee produces large numbers of formed molybdenum and tungsten crucibles and supplies them in all commonly used dimensions. They are successfully used by all the major manufacturers and numerous end customers worldwide.

Electrodes made of molybdenum are used for the melting of glass by means of electrical energy. Plansee molybdenum electrodes have many advantageous properties: high purity, good form stability and high corrosion resistance to molten glass as well as a good electrical and thermal conductivity. Standard sizes are available from stock. Plansee supplies glass melting electrodes made from MoZrO2 for glass production involving particularly aggressive glass melts. Small quantities of zirconium oxide (ZrO2) added to molybdenum enhance the properties of the pure material.
