Homemade ceramic insulators
Has anyone here ever made / heard of someone making their own ceramic insulators? I need to do this for a project and would prefer not to buy two $350+ blocks of machinable ceramic from mcmaster-carr. How would i go about this? I assume there is a powder out there that I would mix with water and pour into a mold, let set up and send it off to be fired. If so, does anyone know where such a powder could be found?
Thanks,
Russ

Doug Coulter makes his own using alumina tubing and others have used pyrex, though the pyrex will reduce and become conductive in a hot hydrogen atmosphere.

To be clear, insulators for what purpose?

If you just want a pure ceramic insulator (no internal metal), isn't that just clay that has been fired with a glass (powder) to create a glass coating? I'd think that wouldn't be too difficult.

Re: Homemade ceramic insulators
Well, no but if spin shaping would work, then clay is easy. Filling a complex mold would be difficult with clay so a powder would make more sense. There are powders that use water but sintering a powder is more difficult - I believe you could google that and get a lot of answers. I've never sintered any powders (have studied the process) but have used clay/glass powder only.

Depending on what your purposes are, Teflon is an excellent HV insulator as well. I have known lots of people to turn Teflon cylinders into DIY HV insulators, myself included.

As a general forum point, better to mention purposes at the outset than keep everyone guessing.Andrew Robinson wrote:Depending on what your purposes are...

Aww where's your sense of mystery haha. Yes I agree though. Ambiguous posts just cause more back and forth and turbulence than required.Chris Bradley wrote:keep everyone guessing.
