1 atm Gas Mixing Furnaces

1 atm furnaces and muffle furnaces are used for sample preparation for analysis and high P&T experiments and for phase equilibria studies.

The laboratory is equipped with two Lenton furnaces (50mm ID worktubes) capable of 1400 and 1800°C, and a precision wound Pt element furnace (1200°C, 25mm ID worktube) equipped with an automatic drop-quench. Controlled oxygen fugacity is achieved by means of CO2/H2 gas mixtures calibrated versus a zirconia oxygen sensor. In addition a Nabertherm muffle furnace (1750°C) is available for sample preparation. The laboratory is also supported by gel-making facilities.

The furnaces operating costs can be provided by the Facility Manager. Access is via discussion with Dr Ian Butler.
