Reasonable Design and Controllable Growth of Instant Boric Acid

Abstract Boric acid is widely used in human life and industrial production. However, few methods for solving the slow dissolution behavior of boric acid are reported. Based on the Density Functional Theory (DFT) analysis, a reasonable modulation strategy is proposed and an effective regulation method is obtained for preparing instant boric acid in this work. The DFT theoretical calculations and various characterizations explain the relation between the exposed surface of crystalline boric acid and its dissolution rate. The experiment results prove that the slow dissolution behavior of boric acid can be dramatically improved by regulating its exposed surface of crystalline particles. This work may fill the lack in the controllable regulation of boric acid crystalline structure and provide new perspectives for improving the dissolution rate of other crystalline products.
