A high-temperature furnace (10) with a wall (1) or chamber defining an inner zone (8), said wall (1) or chamber comprising a refractory material, characterized in that said refractory material comprises molybdenum or a molybdenum compound being protected against oxygen in said inner zone (8) by means of a protective Silicon-Boron (Si-B) coating. Preferably the molybdenum has a purity of at least 99% and acts as a susceptor during induction heating. The furnace can be used for the treatment of waste, biomass, the roasting of ores or minerals, or the conversion of organic materials into synthetic gas. |
