| Material | |||||||||||||||||||||||||||||||||||||||||
| Magnesium oxide is obtained from seawater or by mining from magnesite deposits (magnesite), which are the result of vaporisation of water. The purest form of Magnesium oxide is obtained by processing at high temperatures. Depending on the application Rauschert offers MgO purities of 90% - > 99% and also a selcetion of grain sizes to suit the application (information on request). Porous Steatie and Alumina are also available. |

| Production | |||||||||||||||||||||||||||||||||||||||||
| MgO products are normally produced
by extrusion and can have various shapes and numbers of holes. The parts are
then dried, cut to length and sintered. The hardness of the MgO product can be varied to suit the application. |

| Details regarding the purity of the
different MgO grades are given in the pdf-files, which can be downloaded by
clicking on the appropriate file.
Please note that Acrobat Reader must be installed in order to read the pdf-documents. |

| Applications | |||||||||||||||||||||||||||||||||||||||||
| Due to its high thermal conductivity,
excellent electrical insulation and high melting point MgO is suitable for
high temperature applications. The MgO shapes produced can be supplied in the hard form for heaters and high watt density cartridge heaters or in crushable form for thermocouple, heater cables, fire resistant cables and glow plugs. The shapes formed maintain the separation distance between each conductor, conductor heating element and sheath and also conductor to sheath and or thermocouple. |

| Inquiries | |||||||||||||||||||||||||||||||||||||||||
| For quotations please send us a drawing
of your part together with the purity of MgO, hardness required or application,
tolerances and quantities.
If narrower tolerances are required the parts may have to be machined. |
