Piston Cylinder Apparatus

End-loaded Piston Cylinder mavo press LPC 250-300/50 with 1/2” and 3/4” piston bores similar to the original Boyd-England-Type design. We use talc-pyrex assembly with straight graphite heater and Pt99.95-Pt90Rh10 (S-type) thermocouple for temperature up to ˷ 1400°C; W75Re25-W97Re30 (D-type) thermocouples for T > 1400°C, but oxidizes at P < 11 kbar; and Pt94Rh6Pt70Rh30 (B-type) thermocouples for longer runs at high temperature than S-type, or lower pressure than D-type thermocouples. This high-pressure device can generate pressure range from 0.5 to 3.5 gigapascal (3.5 GPa is equivalent to about 100 km depth in the Earth) and temperatures up to 2000°C and is controlled with manual pressure control for upper and lower pistons.

HEATING UNITS

Being Air-Drying oven

It is used to keep the chemical components dry and to prepare epoxy mounts.

1000°C Ants Furnace

It is used to heat the experimental parts and fire individual experiments' starting materials.

experimental and analytical preparation units

The Lampert PUK arc welder helps to seal the metal experimental capsules to prevent volatile escape. Completed Experimental assemblies are removed from the PC pressure vessel by the Enerpac 10-ton bench press. Mini lathe machine, band saw, and slow speed saw are utilised in machining the experimental parts with precision and to cut the charges of the completed experiments. High-precision balances are used to weigh starting materials. A bench drill is there to create a perfect hole in the insulating mica sheets. To keep the starting materials and the chemicals unaltered and moisture-free, two vacuum desiccators are used.
