Hi,

I want to coat steel tubes/plates with (glass)-ceramic material with extremely high dielectric constant (>5,000). The material must able to withstand voltage at least 3kV/mm.

I have been looking around and sending mails to some companies but to no avail. The closest off-the-shelf product that fits my requirement is piezoelectric tube/plate; only that the electrodes are coated on the surfaces. The electrodes are silver, nikel, or gold which is fine for me.

Does anybody know supplier which supply ceramic tubes or plates with embedded steel or any other conductive metal?

Thanks.
 
I checked their web-sites and I don't think they provide ceramic with high dielectric constant >5,000. This is the main property I am after. The dielectric constant of porcelain enamel is only in the range of 6 to 12.

Anybody here knows how much roughly a piezoelectric tube would cost? If I can't find an alternative, I think I would like to try it if it does not cost much.
