利用粉末X射线衍射数据，用Rietveld法研究了在1450℃真空条件下对二苯二烯进行碳热还原法制备的（Ti1.69Al0.26Fe0.05）3+(Ti0.97Zr0.03)4+O5负沸石的晶体结构。结果表明，其晶格参数为a = 9.8111 Å， b = 3.7509 Å， c = 9.9468 Å， β = 90.628°，为轻度单临床变形的假布鲁克岩型结构。（©2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim）
The crystal structure of anosovite, (Ti1.69Al0.26Fe0.05)3+(Ti0.97Zr0.03)4+O5, prepared by carbothermal reduction of leucoxene under vacuum at 1450°C has been refined by Rietveld method using powder X‐ray diffraction data. It was found that it represents slightly monoclinically deformed pseudobrookite type structure with lattice parameters a = 9.8111 Å, b = 3.7509 Å, c = 9.9468 Å, β = 90.628°.
