Re: [TCML] Titanium dioxide dielectric?

[bturner@xxxxxxxx]

High voltage ceramic caps use Barium Titanate.  And a rather thick
cross-section at that. Trick is to get the oxide into a crystalline
structure. Painting a layer won't cut it - gaps, thin spots, etc. You
don't get a molecularly homogeneous layer.
