  • Molybdenum - Gold Refining Forum

    3/03/2017  The melting point of molybdenum is 4753F, way too high for a gas furnace. With something that hot you not only need a furnace that will get that hot, you need a crucible that will take that much heat without melting. As a reference point, gold melts at 1948F and common carbon steel melts at 2750F.
