Magnesium borate hydroxide (MgBO<SUB>2</SUB>(OH)) nanowhiskers with a diameter of 20–50 nm and a length of 0.5–3 μm were synthesized via a facile hydrothermal route, using MgCl<SUB>2</SUB>·6H<SUB>2</SUB>O, H<SUB>3</SUB>BO<SUB>3</SUB>, and NaOH as the reactants. Mg<SUB>7</SUB>B<SUB>4</SUB>O<SUB>13</SUB>·7H<SUB>2</SUB>O with poor crystallinity was formed after coprecipitation of the reactant solutions at room temperature, the hydrothermal treatment of the slurry at 240 °C for 18 h led to the formation of uniform MgBO<SUB>2</SUB>(OH) nanowhiskers with high crystallinity and preferential growth direction along the (200) plane.
