Abstract/Notes | SummaryKehoeite, a hydrated zinc aluminate-phosphate, produces an X-ray powder diffraction pattern with interplanar spacings similar to those of analcime, viséite, and pollucite. The diffraction maxima appear to be compatible with a cubic (or pseudocubic) lattice with a 13·7 Å. It is concluded that kehoeite is essentially isostructural with analcime and that its framework is composed of linked tetrahedra: (AlO2)−, (H3O2)−, and (PO2)+, as was found to be the case for viséite, which contains (SiO2) in addition. Calculations of the density, the number of oxygens in the unit cell, and the chemical composition are consistent with the structural formula Zn5·5Ca2·5(H2O)32[(Al16P16(H3)16)O96]. |
