摘 要：The growth habit of the basic magnesium oxysulfate whisker was investigated based on the theoreticalmodelof anion coordination polyhedron growth units.It is found that typicalbasic magnesium oxysulfate whisker growth is consistent with anion tetrahedralcoordination incorporation rules.The growth units of basic magnesium oxysulfate whiskers are [Mg-（OH）4]2- and HSO4-.[Mg-（OH）4]2- is the favorable growth unit and whisker growth is in the direction of the [Mg-（OH）4]2- combination.A plurality of [Mg-（OH）4]2- s combine and become a larger dimensionalgrowth unit in a one-dimensionaldirection.Then HSO4- and larger dimensionalgrowth units connect as basic magnesium sulfate whiskers,according to the structuralcharacteristics of the basic magnesium sulfate whisker,which can guide the synthesis of magnesium hydroxide whisker.
