Here's my idea- make/get a carbon electrode. Dip it in sodium silicate or colloidal silica etc to get a very thin glass coating on top. Heat to
above 1350 deg. C to get a thin coating of silicon carbide on top of a graphite rod. The excess glass could be dissolved with HF etc. The SiC layer
should be made thin, because I think graphite is a better conductor.
This is just a random crazy idea of mine. Would this work for chlorate cells or other similar cells?
Also, are there any other chemically oriented uses for SiC where glass or easier solutions won't work?
(I haven't done much research on this, so there are probably a dozen or so flaws in my idea)

SiC is not that immune to chemical attack. I believe hydroxides will turn it into carbonates.

And, in the presence of oxygen, or with the evolution of hydrogen, probably silicates as well.
