Uniform magnesium borate hydroxide [MgBO2(OH)] nanowhiskers with a diameter of 20-60 nm and an aspect ratio of 10-70 were synthesised via a coprecipitation/hydrothermal reaction route, using NaOH, MgCl2 and H3BO3 as the reactants. The experimental results indicated that the control of the Mg/B/Na molar ratio at 2:3:4, the decrease in the NaOH concentration from 2-0 to 0-33 mol L-1, the increase in the hydrothermal temperature from 160 to 240°C and the prolongation of the hydrothermal reaction time from 2-0 to 30·0 h could promote the growth of the MgBO2(OH) nanowhiskers along the c axis, leading to the formation of the MgBO2(OH) nanowhiskers with high aspect ratio.
