First-principles study on the structural and electronic properties of Li4SiO4 and Al-doped Li4SiO4

Fusion Engineering and Design, 2016
Abstract 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, Li3PO4Li4SiO4

Materials Research Bulletin, 1981
Abstract The phase diagram of the system Li4SiO4Li3PO4 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, 2019
Abstract 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, 1992
Radiation 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, 2001
Abstract 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 ...

การผลิตไฮโดรเจนจากแกซิฟิเคชันด้วยไอน้ำของใบอ้อยโดยใช้ NiO/CaO-Li4SiO4

2023
งานวิจัยนี้ทำการศึกษาการผลิตไฮโดรเจนจากกระบวนการแกซิฟิเคชันด้วยไอน้ำของใบอ้อยโดยใช้ NiO/CaO-Li4SiO4 โดยการทดลองถูกดำเนินการในเครื่องปฏิกรณ์แบบเบดนิ่งชนิดสองขั้น จากผลการทดลองพบว่าการใช้ตัวดูดซับลิเทียมออโทซิลิเกต (Li4SiO4) ร่วมกับตัวดูดซับแคลเซียมออกไซด์ (CaO) ผลได้และความเข้มข้นของไฮโดรเจนมีค่าสูงกว่าการใช้ตัวดูดซับลิเทียมออโทซิลิเกตหรือแคลเซียมออกไซด์

Raman spectra of rapidly quenched Li4SiO4Li2WO4 glasses

Journal of Non-Crystalline Solids, 1989
Abstract Glasses were prepared in the pseudobinary system Li4SiO4Li2WO4 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, 2013
Abstract 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.
