摘要：
There is provided a method of producing a mixed metal compound that includes at least Mg2+ and at least Fe3+ having an aluminum content of less than 10000 ppm, having an average crystal size of less than 20 nm (200 Å) comprising the steps of: (a) combining a Mg2+ salt and a Fe3+ salt with Na2CO3 and NaOH to produce a slurry, wherein the pH of the slurry is maintained at from 9.5 to 11, and wherein the Na2CO3 is provided at an excess of 0 to 4.0 moles than is required to complete the reaction (b) subjecting the slurry to mixing under conditions providing a power per unit volume of 0.03 to 1.6 kW/m3 (c) separating the mixed metal compound from the slurry, to obtain a crude product having a dry solid content of at least 10 wt % (d) drying the crude product.
