Dear all,
I knew about the vicor process, but there is still too much sodium in the glass at the end.
I found some papers about preparing a glass in a hot press: Ceramics International, 23 (1997) 291-296.
Production of pure quartz glass is done by
Heraeus:

Corning produces fibres:
http://www.corning.com/opticalfiber/products__services/
Or try:

If you go to google.com and search for high silica fibres you will get a mountain of results!
Has sombody any idea if there has already been tried difussion of metals into silica-based glasses? And if it has worked out? Any helpful internet-sites and publications are welcome.

Dear Bugman,
the problem with Pt-crucible is that it melts above 1736°C!!!!!!!!
Meanwhile we tried some induction melting and that seems to work out quite good.
