pressure vessel

internal heater assembly

machine specifications:

• pressure: 10-200 MPa
• temperature: 300-1500 degree C
• sample volume: max. 0.4 cm3 (5 mm diameter, 20 mm length)*
• quenching operation: rapid quench**
• manufacturer: KOBELCO (Kobe Steel Ltd.)

*temperature gradient over the length of sample estimated to be 10 degree.
**isobaric rapid quench: a sample is hung by thin Mo wire in the hot spot of the internal heater assembly; at the end of experiment, the hanging wire is broken by surge current, thereby letting the sample fall into the cold bottom of the vessel.

applications:

• determination of mineral-melt-fluid equilibria in magma reservoir and conduit
