A new route for the synthesis of Mg2B2O5 nanorods by mechano-chemical and sintering process

Single crystalline Mg2B2O5 nanorods have been synthesized by a two-step process involving the mechanochemical technique and sintering method. Using MgCl2 center dot 6H(2)O and NaBH4 powders as the starting materials. the mixture was firstly milled for 120 h, and then sintered at 800 degrees C for 2 It. The X-ray diffraction indicates the final product is monoclinic Mg2B2O5. SEM and TEM results show that the Mg2B2O5 is nanorod with the diameter about 200-400 nm and the length up to 5 mu m. SAED analysis shows that the nanorod is single crystalline and twinned structure. The by-product NaCl is necessary for the formation of the single phase Mg2B2O5. (C) 2009 Elsevier B.V.
