Crystal chemistry of silica - rich barium silicates II : Electron microscopy of barium silicates containing multiple chains
نویسندگان
چکیده
The phases containing multiple chains in the series Ba",+1[Si2mOsm+d those with triple (m = 3), quadruple (m = 4) and quintuple (m = 5) tetrahedral chains were investigated by high resolution transmission electron microscopy. The resulting images could be correlated with the structures. Variations of the chain multiplicity (m) within single crystals were observed as well as faults in the packing of the multiple chains. The occurrence of sextuple (m = 6) chains suggests, that stable phases with m > 5 could also exist.

Biomimetic mineral self-organization from silica-rich spring waters
Purely inorganic reactions of silica, metal carbonates, and metal hydroxides can produce self-organized complex structures that mimic the texture of biominerals, the morphology of primitive organisms, and that catalyze prebiotic reactions. To date, these fascinating structures have only been synthesized using model solutions. We report that mineral self-assembly can be also obtained from natura...
متن کاملNew insights into the early stages of silica-controlled barium carbonate crystallisation.
Recent work has demonstrated that the dynamic interplay between silica and carbonate during co-precipitation can result in the self-assembly of unusual, highly complex crystal architectures with morphologies and textures resembling those typically displayed by biogenic minerals. These so-called biomorphs were shown to be composed of uniform elongated carbonate nanoparticles that are arranged ac...
متن کاملDisordered mesoporous silicates formed by templation of a liquid crystal ( L 3 )
Figure 1: A sketch of the L3 phase liquid crystal structure, derived from electron microscopy done on freeze fractured samples, as well as theoretical considerations. The pore diameters are uniform, but are randomly interconnected in all three dimensions resulting in short range order with long range disorder. The bilayer forming the liquid crystal can then be templated by a silica layer to cap...
متن کاملThe Utilization of Wheat Hull Ash for the Production of Barium and Calcium Silicates
Wheat is the world's second most produced grain because of its high consumption rate, easy growth, multipurpose use and important role in the human diet. Every year, abundant amounts of wheat hull are obtained after shell process of the wheat as a waste material. Wheat hull, a by-product of the food industry, has low economic value. The utilization of wheat hull ash in various areas of industry...
متن کاملStructural characterization of BaZrO3 nanopowders prepared by stearic acid gel method
Pure barium zirconate nanopowders were successfully prepared in wet-chemistry synthesismethod, using barium stearate and tetra-n-butyl zirconate as Ba, Zr sources and stearic acid ascomplexing reagent. The gel was calcined at 800 and 900 °C in air. Results of thermal analysisare given, including both DTG and TG. Fourier transform infrared spectrometry (FTIR), X-raydiffraction (XRD), transmissio...
