This means that soil solutions in equilibrium with amorphous silica are oversaturated with respect to quartz. Nevertheless, because quartz crystallizes extremely slowly at ambient temperatures, the solubility of amorphous silica effectively sets the upper limit of dissolved silica in natural waters.

The formation of fibrils in poly(carbonate) (PC)/LCP blends have been shown to be enhanced by tbe addition of glass beads. Nano silica acts in the same way. For example, in PC/LCP blends the addition of nano silica results in a reduction of the viscosity. The reduction of viscosity is correlated with the fibrillation of tbe LCP which is promoted by nano silica. In blends of LCP and poly(sulfone) the addition of ca. 5% of nano silica effects the formation of long and perfectly orientated fibrils in the capillary flow. The nano silica forms a network in the matrix that increases the elasticity. This effect is responsible for the improvement of the formation of fibrils.

Trifluoronitrosomethane-tetrafluoroethylene copolymer has good thermal stability. The copolymer does not bum but decomposition into gaseous products begins at about 200°C. The glass transition temperature of the copolymer is -54 C and vulcanizates remain serviceable down to about -40°C. A limitation of the vulcanizates is their low tensile strength, although silica effects some reinforcement.
