Methyltriethoxysilane: New precursor for synthesizing silica aerogels

“…They are highly porous, open cell, low density, nano-structured materials containing as much as 98% air volume and only 2% of silicon dioxide [1][2][3][4]. Therefore, applications of silica aerogels are potentially vast in number such as nuclear waste storage [5], Cerenkov radiation detectors in high-energy physics [6,7], inertial confinement fusion (ICF) targets for thermonuclear fusion reactions [8] and thermal insulation in * Corresponding author.…”

Hydrophobic and low density silica aerogels dried at ambient pressure using TEOS precursor

“…Si(OH) 4 + (OC 2 H 5 ) 4 Si In the surface chemical modification with HMDZ in hexane, the replacement of H from Si OH group by Si R group, where R = alkyl, vinyl or methyl groups. The HMDZ provides the non-polar groups for the surface chemical modification of the gel through the Si (CH 3 ) 3 groups according to the following reactions:…”

“…[2,3]. Due to such versatile and most fascinating properties, the aerogels find several applications both in science and technology such as Cerenkov radiation detectors in high energy physics [4][5][6][7], inertial confinement fusion (ICF) targets for thermonuclear fusion reactions [8], superthermal insulators in solar energy systems, refrigerators, thermos flasks [9,10], as catalytic supports [11], containers for liquid rocket propellants [12], windows for thermal and acoustic insulating systems [13,14]. Traditionally, the solvent in alcogel was removed by achieving supercritical stage to obtain the aerogels.…”

Physical properties of sodium silicate based silica aerogels prepared by single step sol–gel process dried at ambient pressure

“…This porous structure gives rise to several physicochemical properties such as low density (∼0.03 g/cm 3 ), low thermal conductivity (∼0.02 Wm −1 K −1 ), low sound velocity (∼100 m/s) and high surface area (∼1600 m 2 /g) which finds applications in both science and technology like Cerenkov radiation detectors in nuclear reactors and high energy physics [1][2][3], windows for thermal and acoustic insulating systems [4,5], inertial confinement fusion (ICF) targets for thermonuclear fusion reactions [6], containers for liquid rocket propellants [7], superthermal insulators in solar energy systems, refrigerators, thermos flasks and catalytic supports [8][9][10].…”
