Description
The Department of Earh Sciences in Milano has an extensive history in high pressure experimental petrology and geochemistry, maintaining a high pressure laboratory for more than 30 years. At present, we possess a fully-equipped high pressure experimental laboratory boasting one of the largest collections of apparatus in Italy devoted to the synthesis of fluids, minerals and glasses at controlled pressure, temperature and redox conditions. Experimental products aim to reproduce in a small world processes undergoing in the Earth’s interior.
Contacts
Equipment
Rocking press
700 ton O-frame press, programmable 180° overturns
A multianvil module can be exchanged with an end-loaded piston-cylinder module
Capsule-piercing QMS
Volatile content of fluids is analyzed using a capsule-piercing device connected to a quadrupole mass spectrometer (QMS).
The reactor is conditioned with Ar through a five-way valve. The flow rate is selected through a mass flow controller. Lines are heated to 80°C in order to avoid water condensation.
Gas Mixing Vertical Furnace
TMAX= 1800°C
3 gas mass-flow-controllers (two at 0-50 sccm, one at 0-5 sccm)
Oxygen partial pressure is monitored by an extractive ZrO2 sensor
Single stage piston cylinder
Piston of 22 mm diameter
PMAX= 2.0 GPa, T=1400°C
End-loaded piston cylinder
Boyd and England type
PMAX= 4.0 GPa, T=1700°C
Multianvil module
6/8 Walker type multi anvil module on a 1000-ton uniaxial press
WC cubic anvils of 32 mm of edge and with 8 mm, 11mm and 17mm Truncation Edge Length
PMAX = 20 GPa, T=2000°C
