Hydrothermal laboratory

The 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 samples are sealed in Au or Pt capsules. An advantage is that long-term runs can be done to investigate equilibria between solid phases.

200 MPa line:

6 externally heated cold-seal autoclaves (steel: ATS). T-P limits: 800 °C at 200 MPa or 900 °C at 100 MPa. Pressure medium: H2O. The temperature can be controlled via internal or external thermocouples, depending on capsule length. Maximum capsule diameter: 5 mm.

500 MPa line:

12 cold-seal autoclaves (steel: ATS or RENE41). T-P limits: 750 °C at 500 MPa or 900 °C at 100 MPa. Pressure media: H2O (up to 10 autoclaves), or CO2 (2 autoclaves, separate pressure generation unit, to about 400 MPa). The temperature can be controlled via internal or external thermocouples, depending on capsule length. Maximum capsule diameter: 5 mm.

Rapid quench line:

6 rapid quench autoclaves (steel: ATS). T-P limits: 800 °C at 200 MPa or 900 °C at 100 MPa. Pressure medium: H2O. The temperature is controlled via external thermocouples.
