sol-gel glass

sol-gel glass

[′säl ′jel ′glas]
(physical chemistry)
An optically transparent amorphous silica or silicate material produced by forming interconnections in a network of colloidal, submicrometer particles under increasing viscosity until the network becomes completely rigid, with about one-half the density of glass.

The following reagents were used during the sol-gel glass making process without further purification: Tetramethyl- orthosilicate (TMOS) (Aldrich 99+%), ethanol ([C.sub.2][H.sub.6]O) (Sigma-Aldrich, [greater than or equal to] 99.5%), hydrogen chloride (HC1), europium (III) chloride anhydrous (EuCh) (Aldrich, 99.99%), Lab grade tin (II) chloride anhydrous (Sn[Cl.sub.2]), and triple de-ionized water.

Initially, just after the formation of xerogel via hydrolysis and polycondensation, the colour of the glass remained green (the same as the colour of Malachite Green in solution) which turned deep orange with ageing of the sol-gel glass.
Within sections on densification, chemical methods, and physical methods, they discuss such topics as fundamentals and practice of sintering, processing and applications of sol-gel glass, the chemical vapor deposition of structural ceramics and composites, directional solidification, and processing ceramics by plasma spraying.
