Process for producing zirconium based granules
This patent describes a process for the production of amorphous zirconium based granules. It comprises forming a solution comprising Zr(R){sub 4} or zirconyl halide in an alcohol solvent, adding in either order an acid in an amount sufficient to acidify the solution comprising Zr(R){sub 4} or zirconyl halide to a pH in the range of about 2-5 and water in an amount sufficient to hydrolyze the Zr(R){sub 4} or zirconyl halide thereby forming a solution comprising a zirconium based complex; adding about 1-35 wt % of a suitable phase stabilizer to the resulting solution; and drying the solution comprising the zirconium based complex and phase stabilizer at a temperature below about 250{degrees} C. for a time sufficient to evaporate the solution thereby forming zirconium based granules containing the phase stabilizer.
