Abstract
The present invention provides a composite shaped body comprising silica nanoparticles and an organic polymer, wherein the silica nanoparticles and the organic polymer form a three-dimensional network; thereby provides: a composite shaped body which exhibits excellent formability and fabricability and which is also suited for use, for example, in producing a silica glass provided with an electrical conductivity; and a silica glass (especially, an electrically conductive silica glass) obtained by firing the composite shaped body.
Claims26
A composite shaped body, comprising silica nanoparticles and an organic polymer, wherein the silica nanoparticles are dispersed in the organic polymer;
- a nanopore is formed in the organic polymer area;
- and
- a functional element exists all the way from at least a part of a surface of the shaped body to an inner area, to form a doped region.
