Just guessing, I'd say it came from Degussa
(company name, short for Deutsche Gold und
Silber SA). They invented fumed silica
in the quest for developing a "carbon white"
process based on silica, analogous to the
flame process for making carbon black.
When you consider that carbon black is the
main reinforcing filler used in rubber, and
Degussa is a major producer of carbon black,
it could hardly have escaped their notice
that this could be a potential application
thanks! i found this on the web:
is there anything else you know of that sheds a little more light? i've
spent hours on google, but it's mostly propaganda pieces. anything with
a little more meat?
You should be able to reconstruct the history
of this technology from the patent literature,
in as much depth as you want:
You can start with U.S. Patent 4,297,145, searching
both the patents it references and the patents
which reference it.
