Fabrication of Li4SiO4 pebbles by wet method with modified powders synthesized via sol–gel process

Recent advances in lithium containing ceramic based sorbents for high-temperature CO2 capture

“…So far, several Li4SiO4 synthesis methods have been studied, including solid-state reaction, sol-gel, impregnation precipitation, solvo-plasma, spraying drying, and combustion. 31,[52][53][54][55][56][57][58] In addition, new reports on the synthesis of Li4SiO4 from highly porous precursors such as metal organic frameworks (MOFs) and zeolites for CO2 capture were also reviewed. 59…”

“…This superior sorption rate can be attributed to the high dispersion of coated Li4SiO4 particles. 55 Lu et al 56 studied the effect of ball milling on the structure of Li4SiO4 synthesized by sol-gel method. The results showed that average sizes of powders without ballmilling was 3.3 μm.…”

“…In contrast, after ball-milling, the agglomerated large particles were broken down, from 3.3 μm to 102 nm, and the BET specific surface area was significantly increased from 0.4 to 4.9 m 2 g -1 . 56,69 Carbon coating method has been applied to the modification of solid-state method. Zhao et al 70 showed that this method can also be applied to the Li4SiO4 synthesized by sol-gel method.…”

Sol‐gel synthesized lithium orthosilicate as a reusable solid catalyst for biodiesel production

“…To prepare Li 4 SiO 4 using the sol‐gel method, LiOH•H 2 O was dissolved in an aqueous solution containing SiO 2 at different molar ratios of LiOH to SiO 2 (4.1:1‐4.5:1). Citric acid (C 6 H 8 O 7 :SiO 2 molar ratios from 1.3:1 to 1.7:1), acted as a chelating agent, was then added to the reaction solution to synthesize a homogeneous particle size and fine powder 25,30 . The solution was stirred and the resulting colloidal solution was subsequently vaporized at 100°C to form a gel.…”

A facile approach to fabricate Li4SiO4 ceramic pebbles as tritium breeding materials

“…Subsequently, the slurry was dropped into liquid nitrogen through a nozzle, and green spheres were formed because of the effects of surface tension. The green bodies were dried in a forced convection oven after placing in air for a certain time [14]. Finally, the Li 4 SiO 4 ceramic pebbles were obtained by sintering the green spheres at 800°C for 4 h.…”
