| abstract |
A process for preparing spheroidal aggregates of platy hydrotalcite particles having a predetermined average aggregate size comprising the steps of: (a) forming an aqueous magnesium ion-containing solution; (b) forming an aqueous aluminum ion-containing solution; such that the molar ratio of magnesium ions in the solution of step (a) to the aluminum ions in the solution of step (b) is in the range of from 2.25:1 to 4.5:1; (c) forming an aqueous basic solution containing an excess of carbonate and sufficient total base to maintain a reaction mixture of the solutions prepared in steps (a), (b) and (c) at a pH in the range of from 8.5 to 9.5; (d) mixing the solutions prepared in steps (a), (b) and (c) with water at a temperature of from 20 DEG C to the mixed solution boiling point, by adding the solutions to the water over a period of time of from 0.5 to 8.0 hours, at constant temperature, with the rate of addition of each solution being constant over the period of addition; and with continuous stirring at a constant rate sufficient to produce homogeneous mixing and to impart an amount of shear required to produce the desired aggregate size; and (e) recovering product hydrotalcite crystals from the reaction solution. |
