Not entirely sure this is the right place, but here goes.
I've been looking for a high temperature ceramic to pot sensors/heater cartridges, as well as fixate them in place and so on.
Ceramic would need to be electrically insulative and thermally conductive.
Unfortunately every darn ceramic potting compound I can find reports ridiculously low thermal conductivity, something like 3W/m-K or 5W/m-K.
Even when base materials are a 40W/m-K or better......
I've been considering using 325 mesh or smaller ceramic powder (aluminum oxides, MgO, etc.) and some kind of non-water carrier. Armco sells, HLB-1 whatever that is.
There's certainly more that goes into it such as dispersants and what not, I've no clue on it and was hoping for an off the shelf solution that didn't suck thermally.
If anyone with more understanding of the chemistry involved could assist that would help greatly

I, for one, don't understand why all these compounds claim 'Huge thermal conductivity' and then absolutely suck.
