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

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

A New Approach for the Production of Li4SiO4 Powder

2020
Li4SiO4 is a promising material for CO2 capture at high temperatures. A high capture capacity up to 36.7 wt% between 450 and 700 °C, fast carbonation/decarbonation kinetics, good mechanical properties, and also cyclic usage can be counted as the advantages of this solid.

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 ...

Study of adsorption and desorption of water on Li4SiO4

Journal of Nuclear Materials, 1989
Abstract Lithium orthosilicate is one of the candidate materials for tritium breeding in a fusion reactor blanket. The release of tritium from this material depends on diffusion in the bulk and on desorption from the surface of the material which is usually covered by adsorbed water.

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.

Measurements of the effective thermal conductivity of a bed of Li4SiO4 pebbles of 0.35–0.6 mm diameter and of a mixed bed of Li4SiO4 and alu

Journal of Nuclear Materials, 1992
The Karlsruhe ceramic breeder reference design for a Demo relevant blanket is based on a concept where the breeder material is in form of a bed of a mixture of Li 4 SiO 4 pebbles in the diameter range 0.35–0.6 mm. The heat transfer parameters of this bed have been measured in an especially developed experimental apparatus.

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.
