New Facile Method for the Preparation of M3B7013I Boracites (M = Mn, Fe, Co, Ni, Cd).

Five iodine boracites, M3B7O13I (M = Mn, Fe, Co, Ni, Cd), have been synthesized by reactions of metal oxide, B2O3, element B, and I2 at intermediate temperature above 350 °C. Powder X-ray diffraction analyses verify the identities and purity of the products, which are also confirmed by magnetic property measurement Except safe, cheap, and convenient, this novel method is significandy flexible in the selection of the starting metal oxide. The influence of the reaction temperature and time has also been studied. [ABSTRACT FROM AUTHOR]
