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.
