Processes for producing supported zinc dimolybdate hydroxide/silica complexes include the steps of reacting a zinc compound (such as zinc oxide) and molybdenum trioxide in an aqueous system to form a reaction mixture, and contacting the reaction mixture with silica to form the supported zinc dimolybdate hydroxide/silica complex. The resulting supported zinc dimolybdate hydroxide/silica complexes contain silica and zinc dimolybdate hydroxide at an amount in a range from 3 to 20 wt. % zinc, and generally, at least 80 wt. % of the zinc dimolybdate hydroxide is present in the form Zn.sub.3Mo.sub.2O.sub.8(OH).sub.2. These supported zinc dimolybdate hydroxide/silica complexes are useful in polymer compositions, such as PVC-based and epoxy-based formulations.
