Glass has been preferred as a column material because of its more inert character. Fused silica is a high purity glass that is composed of essentially silicon and oxygen. It is the type of glass that is most inert, has the best flexibility, and produces the most uniform product that responds most predictably to subsequent coating (8). Fused silica is therefore the material of choice for capillary IGC experiments. 

The hydrolysis and condensation of silicon alkoxides is an area of intense interest. The sol-gel process uses high-purity monomers for low-temperature production of fibers, monoliths, coatings, and powders. Structures of the polymers produced in the sol ultimately dictate both gel and glass properties.

Yajima [76] was the first to study the preparation of silicon carbide fibers from carbosilanes. These and other SiC-containing polymers were used to produce SiC powders with a crystallite size as small as several nanometers [77, 78]. The advantage ofthe production route from liquid to solid to produce SiC has also attracted attention for SiC film production in microelectronics or as protection layers. In this way, amorphous, polycrystalline films of high purity produced by the dip-coating of substrates in PCS solutions and subsequent pyrolysis in an inert gas atmosphere, have been prepared [115]. 

However, in the electrolysis of melts containing TiCl2, a metallic coating is formed on the walls of the container (Si02), and the cathodic metal has high purity with respect to silicon.This metal formation is stated [5] be due to disproportionation ...
