摘要: A novel molybdenum compound, ammonium dodecamolybdomolybdate (AMM), is described which may be used in the manufacture of molybdenum metal and molybdenum carbide powders. The molybdenum compound is a dodecaheteropoly acid salt having a Keggin-type structure wherein molybdenum resides in both the hetero as well as peripheral atomic positions. The novel compound has the general formula (NH4)2Mo12MoO40.6H2O. Because of its low solubility, the compound can be crystallized efficiently and at a high purity from ammonium molybdate solutions.

摘要: The present invention provides a method for fluidized bed roasting of molybdenite to molybdenum trioxide. A fluid bed reactor separated into separate zones is used to provide plug flow conditions. A cooling tube is submerged in the fluid bed to control temperature. A vibrator is used to enhance fluidization.
