Hi Group

quite a lot of effort has been made to gel liquid rocket fuels. On the
oxidizer side I only know about gelling nitric acids. What has been used
for that? Fumed silicas?
What about gelling N2O4? Has that been done and how. Many thanks for any
infos and pointers to websites or publications (specially the NTO issue)

Yup. Cabosil, available at your local plastics place, will do the trick.
