Název v původním jazyce

Synthesis and stability of some members of the pharmacosiderite group, AFe4(OH)4(AsO4)3.nH2O (A = K, Na, 0.5Ba, 0.5Sr)

Popis výsledku v původním jazyce

Samples of the pharmacosiderite group were synthesized either directly, from aqueous solutions, or by ion exchange over extended periods of time. In more than 200 experiments, no pure pharmacosiderite sample was obtained, and a protocol was developed to remove scorodite and arsenical iron oxides from the samples. In this way, K-, Na-, Ba-, and Sr-dominant pharmacosiderite samples were prepared. The chemical compositions of the two samples used for further experiments were Ba0.702Fe4[(AsO4)0.953(SO4)0.047]3(OH)3.455O0.545.5.647H2O and K1.0861.086Fe4[(AsO4)0.953(SO4)0.047]3(OH)3.772O0.228.4.432H2O. In t his work their properties and crystal structure were studied and the results are presented.n
