One-Atmosphere Gas Mixing Furnaces

Next to conventional high temperature box furnaces, we employ vertical gas mixing furnaces for heating at controlled oxygen fugacities. Such furnaces are an indispensable tool in experimental methods; they allow expriments or just synthesis of starting materials to be perfomed under a wide range of redox conditions. The gas atmosphere can be adjusted using CO₂ - H₂ mixtures at temperatures up to 1650°C to simulate reducing or moderately oxidizing conditions as they are applicable for a wide range of metamorphic, magmatic or tectonic environments. Note, that for safety reasons we do not employ mixtures of commonly used CO₂ and highly toxic CO. However, our lab is nontheless monitored by CO gas sensors.
