GFZ - German Research Centre for GeosciencesThe hydrothermal laboratory is equipped with horizontal and vertical cold-seal pressure vessels for the synthesis of crystals or glasses or to study interactions between minerals/rocks, melts, and fluids at hydrostatic conditions. The hydrothermal lab comprises three lines: 200 MPa line, 500 MPa line and rapid quench line.
GFZ - German Research Centre for GeosciencesIn principle, an internally heated pressure vessel (IHPV) consists of a thick-walled pressure vessel sealed by closure plugs at the ends. In addition, there is a pressure inlet/outlet as well as several electrical leads into the vessel for power supply to and temperature control of the internal furnace. The equipment is particularly designed for experimental studies at medium to high temperatures (currently up to 1250 °C) and pressures up to 10 kbar. This P-T range is inaccessible by …
GFZ - German Research Centre for GeosciencesThe static 1000 t laboratory press of Max Voggenreiter GmbH can be operated either with a Walker module as a multi anvil press or via a second hydraulic cylinder with a piston cylinder module (diameter 12.7 mm).
GFZ - German Research Centre for GeosciencesTo investigate the pressure/temperature regime of the Earth´s crust and shallow parts of the upper mantle, at the GFZ three piston cylinder presses are installed and run. Two of the three presses are non-endloaded piston cylinder apparatus ("Johannes-type"), with which pressures up to 2.1 GPa and temperatures up to 1400 °C can be reached. Salt/graphite- or natural fluorite/graphite-assemblages (latter for temperatures larger 800 °C) are of 2.2 cm diameter. Pressures were calibrated according …
GFZ - German Research Centre for GeosciencesA Rotating Multi-Anvil Press constructed by Max Voggenreiter GmbH is installed in the high-pressure hall of the GFZ. The apparatus consists of an 800 tons hydraulic press and a Walker-type multi-anvil module. The whole apparatus is rotatable by 360° perpendicular to the press axis. Schmidt and Ulmer (2004) demonstrated that by rotation it is possible to overcome common fluid/solid or melt/solid separation during high-pressure experiments. The press …
