Size, shape-controlled Synthesis of BaSiF_6 nanostructures in a hydrothermal process

摘要

Different sizes and shapes of BaSiF_6 were synthesized by a low temperature hydrothermal method using citric acid (CA) as a chelating agent and cetyltrimethylammonium bromide (CTAB) as a surfactant. The sizes and morphologies of the BaSiF_6 could be altered by controlled the molar radio of CA to Ba~(2+). And the CTAB could help to fabricate nanoscale crystals. The as-synthesized BaSiF_6's properties were studied using XRD, SEM, TEM and Raman. Finally, the mechanism for CA and CTAB coactive hydrothermal synthesis of the BaSiF_6 is discussed.
