It is an intemiediate product of oxidation between iron sulfides and sulfates, fonning monoclinic, colourless to pale yellow, transparent crystals with a vitreous lustre. The mineral occurs associated with stolzite, pyromorphite, hinsdalite, plumbogummite, gibbsite, scheelite and jarosite on ...
Metal ion binding studies of 1 have been performed in CH3CN/H2O (3:1, v/v, 10 mM Tris-HCl buffer, pH = 6.90). Compound 1 senses multiple metal ions such as Al3+, Fe3+ and Fe2+ by exhibiting turn on fluorescence and colour change (colourless to pink) under different experimental ...
Vochtenite is brown in colour with a bronzy lustre and is non-fluorescent. Mohs hardness is 2.5 and the density (calc.) = 3.663 g/cm. There is a prominent (010) cleavage. Vochtenite is optical biaxial negative, 2V (calc.) = 89(3)° its dispersion is indiscernible. Refractive ...
Optically, almarudite is uniaxial negative, with n= 1.560(1) and n= 1.559(1) and a strong pleochroism from orange (//n) to colourless (//n). Electron microprobe analyses yielded (wt.%): NaO 0.66, KO 4.05, BeO 5.18, MgO 1.51, CaO 0.12, MnO 7.31, FeO 4.48, ZnO 0.24 AlO72.31...
