Synthesis of magnesium borate nanorods

Single-crystalline magnesium borate Mg2B2O5 nanorods have been synthesized via a simple route based on the calcinations of mixed powders containing Mg(OH)2 and H3BO3. The nanorods have the typical diameters in the range of 70–120 nm and the lengths up to a few micrometers. An optimal synthesis temperature for Mg2B2O5 nanorods was obtained, and the possible growth mechanism was also presented.
