摘要： The present disclosure provides a method for in-situ synthesizing tungsten carbide powder. In this method, cemented carbide scrap is used as an electrode and the molten salt electrolysis process is used to in-situ synthesize tungsten carbide powder, where a bidirectional pulse is used in the molten salt electrolysis process. In the method provided by the present disclosure, by using the bidirectional pulse and using the cemented carbide scrap as electrode in the molten salt medium, when the tungsten carbide scrap is oxidized, tungsten is dissolved in ionic form, deposited after the direction of current changes, and reacted with the carbon anode sludge in situ to generate tungsten carbide powder. In the present disclosure, the carbon anode sludge is treated appropriately, the recycled product can be used in upmarket application, there is no need to apply complicated processes to process the tungsten powder into tungsten carbide, and the tungsten carbide nanopowder with high-performance can be recycled and prepared in a short process.

摘要： Processes for producing ammonium octamolybdate/metal hydroxide complexes include the steps of pre-contacting ammonium dimolybdate and a metal hydroxide, and then contacting molybdenum trioxide, to form the ammonium octamolybdate/metal hydroxide complexes. The resulting complexes contain the metal hydroxide and from 1 to 95 wt. % of ammonium octamolybdate, and generally, at least 80 wt. % of the ammonium octamolybdate in the complex is present in an orthorhombic crystalline form. These ammonium octamolybdate/metal hydroxide complexes can be used as smoke suppressants in polymer compositions, such as PVC-based and epoxy-based formulations.
