Die Kristallstruktur von Li4SiO4
Monatshefte f�r Chemie, 1968Die Kristallstruktur des Lithiumorthosilicats wurde mittels dreidimensionaler Fourier-Synthesen und nach der Methode der kleinsten Quadrate bestimmt. Die Gitterparameter der monoklinen Elementarzelle (C 2h 2 −P21/m) betragen:a=5,14;b=6,10;c=5,30 A und β=90,5°.

First-principles study on the structural and electronic properties of Li4SiO4 and Al-doped Li4SiO4
Fusion Engineering and Design, 2016Abstract The structural and electronic properties of Li 4 SiO 4 and Al-doped Li 4 SiO 4 have been investigated using first-principles density functional theory. The crystal structure is fully relaxed. It can be concluded that the crystalline structure has been expanded as Al doped. The calculated total energies indicate that the Al atoms may occupy

The solid electrolyte system, Li3PO4Li4SiO4
Materials Research Bulletin, 1981Abstract The phase diagram of the system Li4SiO4Li3PO4 has been studied. At subsolidus temperatures, ≲ 1000°C, Li4SiO4 forms a short range of equilibrium solid solutions between 0 and ∼ 12 mole % Li3PO4; γ-Li3PO4 forms a range of equilibrium solid solutions between ∼ 58 and 100% Li3PO4. In addition to these equilibrium solid solutions, Li4SiO4 forms

Tritium release behavior of Li4SiO4 and Li4SiO4 + 5 mol% TiO2 ceramic pebbles with small grain size
Journal of Nuclear Materials, 2019Abstract The tritium release behavior of the Li4SiO4 pebbles and Li4SiO4 + 5 mol% TiO2 pebbles with small grain sizes was investigated. The tritium release results of Li4SiO4 pebbles with different grain sizes (0.3 μm and 1.5 μm) indicated that the grain size had little effect on the tritium release regardless of the difference in gas composition of ...

Radiation damage in pure and Al-doped Li4SiO4
Journal of Nuclear Materials, 1992Radiation damage in Li4SiO4 and Li3.7Al0.1SiO4 irradiated with 120 MeV oxygen ions was investigated by measuring the ionic conductivity and the Raman spectra. The conductivity of Li4SiO4 in the post irradiation condition increased with the fluence in the temperature range 413 to 613 K.

Thermal creep of Li4SiO4 pebble beds
Fusion Engineering and Design, 2001Abstract The description of thermal creep in ceramic breeder pebble bed blankets is of large importance for the calculation of the bed-structure mechanical interaction (BSMI) which is important for the assessment of the blanket lifetime. Results of thermal creep experiments with Li4SiO4 pebble beds (pebble diameters between 0.25 and 0.63 mm) are ...

Raman spectra of rapidly quenched Li4SiO4Li2WO4 glasses
Journal of Non-Crystalline Solids, 1989Abstract Glasses were prepared in the pseudobinary system Li4SiO4Li2WO4 by a rapid quenching technique. The Raman spectra showed that not only monomer SiO44− and WO42− ions but also condensed structural units such as Si2O76− and WO6 groups were present in these glasses over the whole glass-forming region of 0–90 mol% Li2WO4. The condensed structurel

Mass loss of Li2TiO3 pebbles and Li4SiO4 pebbles
Fusion Engineering and Design, 2013Abstract It has been known that water vapor is released from ceramic breeder materials into the purge gas due to desorption of adsorbed water under dry atmosphere and due to the water formation reaction under hydrogen atmosphere. However, an effect of water vapor in the purge gas to Li mass loss has not been understood.
