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 کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
