Tritium release property of Li2TiO3-Li4SiO4 biphasic ceramics

Journal of Nuclear Materials, 2020
Abstract The tritium release experiments of Li4SiO4 pebbles, Li2TiO3 pebbles and Li4SiO4-Li2TiO3 biphasic pebbles were conducted to investigated the tritium release behavior of Li4SiO4-Li2TiO3 biphasic pebbles. The results indicate that the biphasic ceramic pebbles with uniform structure and small grain size exhibit good tritium release performance ...

Studies on Li2SO4-MgSO4 and Li2SO4-Li4SiO4 systems

Acta Chimica Sinica, 1986
The phase equilibria as well as the properties and crystal structures of the compounds formed in both Li2SO4-MgSO4 and Li2SO4-Li4SiO4 systems have been studied by means of x-ray diffraction technique (at high and room temperatures) as well as by the thermal analyses (DTA, DSC, TGA, etc.). In Li2SO4-MgSO4 system there exists a compound Mg4Li2(SO4)

Semi-industrial production of li4sio4 powder and spheres

Fusion Engineering and Design, 1989
This report deals with the preparation of a 70 kg batch of lithium orthosilicate. For synthesis, a technique has been selected under which the LiOH and SiO2 starting materials form a preliminary product in methanol. The resulting suspension is spray-dried after water has been substituted for alcohol.

Synthesis and electrochemical properties of Li2S–B2S3–Li4SiO4

Solid State Ionics, 2006
Abstract New Li + ion-conductive glasses Li 2 S–B 2 S 3 –Li 4 SiO 4 were synthesized by rapid quenching, and they were transformed into glass ceramics by heat treatment. The heat treatment increased the ionic conductivities of the Li 4 SiO 4 -doped glasses, and the highest ionic conductivity observed in the system was 1.0 × 10 − 3 S cm − 1 at ...

Chemical synthesis and characterization of lithium orthosilicate (Li4SiO4)

Materials & Design, 2001
Abstract A solution based wet chemistry approach has been developed for synthesizing Li4SiO4 powders at moderate temperatures of 500°C. LiOH·H2O and LiNO3 have been used as starting materials for synthesizing this material in the present study. The phase evolution behavior, surface area and morphology of the as-prepared and heat treated powders ...

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.

Porous extruded-spheronized Li4SiO4 pellets for cyclic CO2 capture

Fuel, 2019
Abstract In this work, spherical Li4SiO4 pellets were produced via an extrusion–spheronization technique. This pelletization process caused the destruction of the original porous structure, a reduction of the specific surface area and, thus, a decrease in the CO2 sorption performance.

Molecular dynamics simulation of Li4SiO4 melt and glass

Journal of Non-Crystalline Solids, 1987
Molecular dynamics simulation has been carried out on Li4SiO4 melt and glass. The computer-generated structures of Li4SiO4 melt and glass seemed to be realistic in comparison with our Raman and X-ray diffraction data. The simulated correlation functions were in satisfactory agreement with the one obtained from the X-ray diffraction analysis ...

Ionic conductivity of oxides based on Li4SiO4

Journal of Applied Electrochemistry, 1973
Lithium orthosilicate, Li4SiO4, and its solid solutions are a new group of solids of high ionic conductivity. Either Li or Si may be at least partially replaced by several other di-, tri- or tetra-valent cations. Highest conductivities were found for solid solutions with Si partially replaced by Ti; typical values were 10−3 to 10−4 Ω−1 cm−1 at 300°C ...

Li+ ion conductivity in the system Li4SiO4Li3VO4

Journal of Solid State Chemistry, 1984
Abstract Two ranges of solid solutions were prepared in the system Li 4 SiO 4 Li 3 VO 4 : Li 4− x Si 1− x V x O 4 , 0 x ≲ 0.37 with the Li 4 SiO 4 structure and Li 3+ y V 1− y Si y O 4 , 0.18 ≲ y ≲ 0.53 with a γ structure. The conductivity of both solid solutions is much higher than that of the end members and passes through a maximum at ∼
