Crystal Structure and Chemical Composition of BIMEVOX (ME=Mn)

摘要：

The Bi2MnxV1-xO5.5-δ powders were synthesized by high temperature melting method. The effect of Mn dopant concentration on the crystal structure and chemical composition was studied. The crystal structure was determined by X-ray powder diffraction. The chemical composition was tested by X-ray fluorescence (XRF) and Energy Disperse Spectroscopy (EDS). When x < 0.2 the Aurivillius structure solid solution coexisted with few BiV04. When 0.2≤x≤0.3 the γ-phase Bi2MnxV1-xO5.5-δ solid solution with tetragonal structure formed and the maximum Mn atomic content was 2.14％. When x≥0.4 the manganese oxide secondary phase appeared. And when x = 0.8 the Bi7VO13 structure solid solution formed while the Aunvillius structure disappeared.
