Cant seem to find a kv/mm for waterglass/sodium silicate. I was thinking of using it as an electrical insulator for vacuum feedthroughs, expecting an easy seal as I hear it expands when heat cured, therefore pushing against the chamber wall and the wires to prevent leaks and also seal by its adhesive properties. I think of using spark plugs but 50kv is too much for them.
