DavidI recommend dipped silver mica. Ceramics exhibit a piezoelectric behavior when hit with a hard transient. Mica's are stable with respect to time, temperature, and electrical stress, and they are fairly low-leakage.
I'm also not sure that you will be able to find the better ceramic dielectrics at the voltages you need, but check on this.
