You are really funny guys ! Even this subject has a little fun, it was
much simple if any piclister from NZ send to Joe some metalized piezos, I
could do this, but will take three weeks or a whole month from here...
BTW any metalizing technology without vacuum ( like you proposed here
) will have no adherence with the piezo surface. If the final device will
be just a toy it's OK, else for an ultrasonic transducer ( like Joe
pointed in his ask ) all you've talking here it's a good joke, execept
probably high temperature silver paste and repolarising treatment...
A vacuum chamber for metalizing is not wery hard to built for an amateur,
if you have a vacuum pump up to 10exp-5 barr and a little vaporisation
resistive owen ( 12V 10...20 Amp )Don't forget to use some mask else
everything in the chamber will be metalised.  Aluminium may be vaporised
easyest but is difficult to solder on aluminium thin film...anyway is
better than soldering on to ceramic surface directly...
Who knows, Joe it's a very good experimenter and I like his problems !
