Fabrication of Li4SiO4 pebbles by a sol–gel technique

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

“…In the TG curve, four major weight losses regions were observed at four different temperature ranges. The loss of mass of the sample from 267°C to 712°C could be mainly ascribed to the removal of bonded water, decompositions of the metal citrate in the precursor and the formation of new phases [21,40]. In DTG curves, significant peak at 283.4°C can be associated with the removal of bonded water, the carbonization of the gel and the formation of Li 2 CO 3 .…”

“…The density of the pebbles dropped slightly when further increased the temperature to 950°C, which might be caused by the formation of small amount of impurities. At the temperature from 900 to 950°C, lithium ceramics began to lose lithium and decomposed into other lithium compounds [40,[51][52][53]. Cruza et al had demonstrated that the Li 4 SiO 4 began to decompose into small amounts of Li 2 SiO 3 (about 8%) after sintering for 30 min at 900°C [54].…”

The effect of γ-radiation in Li4SiO4 ceramic breeder blankets

“…Li 4 SiO 4 ceramic is considered a potential good candidate because of its compatibility with structural materials, release performance of bred tritium and high melting point [11]. In order to identify the microstructural modifications and provide reliable data on the variation of electrical properties, this paper conducts a detailed analysis on the changes induced after ␥-irradiation at different doses and varying experimental conditions.…”

Fabrication and characterization of Li4SiO4 pebbles by melt spraying method

“…There are many methods for the ceramic pebble fabrication, such as, sol-gel, extrusion/spheronization, wet method, agglomeration and melt-spraying [4][5][6][7][8]. Actually, sol-gel, extrusion/spheronization, * Corresponding author.…”
