The Department of Mineral Sciences maintains two vertical Deltech DT-31-VTHN-C one- atmosphere gas-mixing furnaces. The furnaces operate from room temperature to 1800°C and the partial pressure of oxygen within the furnace can be precisely controlled over ~10 orders of magnitude by CO-CO₂ gas mixtures. Materials subjected to high temperature can be rapidly quenched to room temperature or to a water bath while remaining in the controlled atmosphere by means of a remotely operated integrated drop-quench system.
The lab also features the following capabilities:
Puk3 Professional Welder with neutral Ar gas flow and precision-welding with microscope assistance
Capability to evacuate and seal silica glass tubing
Noble metal wire and tubing and ceramics for encapsulation
The furnaces are in routine use for investigation of phase equilibria, geochemical kinetics, and redox processes in planetary materials.
