Crystallization under supercritical conditions in aerogels

Effect of different weightage of Enova® IC3100 silica aerogel on aluminium alloy composites in ISO2685 aviation standard fire-test

“…Enova ® IC3100 is among the type of silica aerogels made synthetically, it has properties that form an open nanostructure by interconnected particles of size 2-4 nm, thermal conductivity of 0.012 W/mK, density of 124 kg/m 3 and a specific surface area of 901 m 2 /g (Gorle et al, 2008;Lu et al, 1995). The Enova ® IC3100 is hydrophobic in nature with low gas convection and solid conduction.…”

Potential SiO2/CRF bilayer perturbation aerogel target for ICF hydrodynamic instability experiment

“…The results showed that the peak values of pore size distribution of CRF and SiO 2 aerogel sheet were about 31 and 12 nm while its average pore size were 3.09 and 2.01 nm. Compared with the pore size distribution of bulk CRF and SiO 2 aerogel [23,24], the pore size distribution of CRF and SiO 2 aerogel sheet was similar with it. By adjusting the stoichiometry of the precursor and the preparation process, different density and microstructure of CRF and SiO 2 aerogel sheet could be achieved for the needs of bilayer perturbation aerogel target.…”

Preparation and Characterization of Integrated Bulk of Silica Aerogels

“…Moreover, vast waste liquid will be produced owing to the usage of large number of solvents, which can cause environmental pollution and large time will be cost when drying at ambient pressure. Therefore, further studies on supercritical drying technique are necessary for actual application of pure silica aerogels 18,19 . In this study, integrated bulk of pure silica aerogel was prepared from tetraethoxysilane precursors by supercritical drying technique, its structure and properties were characterized in detail via different analysis technique.…”
