We would appreciate ANY info RE: a material and/or process to seal (from
water
absorption) and also electrically insulate a piezo-electric ceramic
crystal,
to be used for Ultrasonic flaw detection in hostile environment:
-Lithiated heavy water (Ph-10) at 300@ C, 1500psi. (10MPa)
-High radiation fields (>1 Mrads gamma + neutrons)

We have tried Cotronics Inc. ceramic adhesive & sealants but the curing
process 
does not lend itself well to this assembly.
