Neutron Spectroscopic Study of Synthetic Alunite and Oxonium-substituted Alunite
Synthetic, polycrystalline samples of alunite [K0.88(H3O)0.12Al2.64(SO4)2(OH)4.92(H2O)1.08] and oxonium-substituted alunite [H3OAl2.87(SO4)2(OH)5.61(H2O)0.39] have been investigated using incoherent, inelastic neutron-scattering (IINS) methods in order to determine the nature of the non-OH “H2O”. IINS measurements were made on non-deuterated samples at 20 K using the HRMECS chopper spectrometer...
متن کاملAlunite supergroup: recommended nomenclature
Minamiite has been discredited and renamed natroalunite-2c to show a double unit-cell structure and natroalunite can be designated as natroalunite-1c to show a single unit-cell structure. Kintoreite can be designated as kintoreite-1c to show the same single unit-cell structure, and IMA 1993-039 is a new superstructure of kintoreite and can be designated as kintoreite-2c to show a double unit-ce...
متن کاملIdentification of Calcium Sulphoaluminate Formation between Alunite and Limestone
This study was carried out to identify the conditions of formation of calcium sulphoaluminate (3CaO·3Al(2)O(3)·CaSO(4)) by the sintering of a limestone (CaCO(3)) and alunite [K(2)SO(4)·Al(2)(SO(4))(3)·4Al(OH)(3)] mixture with the following reagents: K(2)SO(4), CaCO(3), Al(OH)(3), CaSO(4)·2H(2)O, and SiO(2). When K(2)SO(4), CaCO(3), Al(OH)(3), CaSO(4)·2H(2)O were mixed in molar ratios of 1:3:6:3...
متن کاملUse of Raman spectroscopy to characterize and distinguish minerals of the alunite supergroup
The alunite supergroup consists of more than 50 representative minerals with the general formula A B 3 (XO 4) 2 (OH) 6 , where A may be occupied by Na, is the trivalent cation , Al 3+ or Fe 3+ , but also Cu 2+ or Zn 2+ and X is the tetrahedral anion, S, P or As [1, 2]. The minerals of this supergroup form numerous complex solid solutions which crystallize in a rhombohedral system, space group R...
متن کاملClay Mineralogy and Chemistry of Halloysite and Alunite Deposits in the Turplu Area, Balikesir, Turkey
A field-mapping and crystal-chemical study of two aluniteand halloysite-rich deposits in the Turplu area, situated northwest of Balıkesir on the Biga Peninsula of northwest Turkey reveals a mineralogically diverse and a potentially economic clay deposit. The mineral assemblage along fault zones is dominated by halloysite and sometimes alunite. The alunite is nearly end-member in composition (a ...
