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 ...

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.

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 ...

Mechanical behavior of Li4SiO4 in a blanket typical geometry

Fusion Engineering and Design, 2000
The mechanical behavior of the granular ceramic breeder material is of importance for the integrity of any solid breeder blanket concept. Finite element calculations for blanket relevant conditions are performed using methods from soil mechanics. These account for volume compaction during compression and for shear failure i.e.

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.

Fabrication of Li4SiO4 pebbles by a sol–gel technique

Fusion Engineering and Design, 2010
Abstract Li4SiO4 pebbles are considered as candidate ceramic breeder materials in many blanket designs. In this work, Li4SiO4 pebbles with adequate sphericity were fabricated by a water-based sol–gel process using LiOH and SiO2 (aerosil) as the raw materials, which has not been reported for fabrication of Li4SiO4 pebbles previously. Thermal analysis,

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.
