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 ...

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 ...

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

New Li+ ion conductors in the system Li4SiO4−Li3AsO4

Solid State Ionics, 1982
Abstract In the system Li4SiO4-Li3AsO4, Li4SiO4 forms a short range of solid solutions containing up to 14 to 20% Li3AsO 4, depending on temperature, and γ-Li3AsO4 forms a more extensive range of solid solutions containing up to ≈55% Li4SiO4. The Li4SiO4-Li3AsO4 phase diagram has been determined and is of binary eutectic character.

A new synthesis route to Li4SiO4 as CO2 catalytic/sorbent

Catalysis Today, 2005
Abstract An alternate method for the synthesis of a carbon dioxide (CO 2 ) capture catalytic/sorbent, Li 4 SiO 4 , has been developed. This method consists in mixing two precursors in a solid suspension, one being incorporated in an aqueous solution (LiNO 3 ) and the other in a suspended phase (SiO 2 ).

Elucidating the promotion of Na2CO3 in CO2 capture by Li4SiO4.

Physical chemistry chemical physics : PCCP
Although Li4SiO4-based sorbents are candidates for CO2 capture at high temperatures, it is still necessary to improve their kinetic activation for adsorption and desorption. Carbonate doping to Li4SiO4 is considered as one of the effective means to improve CO2 capture by Li4SiO4.
