Method for making electrode connections to potassium tantalate-niobate

Claim 1

THE METHOD OF PREPARING THE SURFACE OF A CRYSTAL WHOSE COMPOSITION IS WITHIN THE POTASSIUM TANTALATENIOBATE SYSTEM COMPRISING SUBJECTING AND SURFACE TO AN ETCHING PROCESS TO REMOVE DAMAGED PORTIONS; MODIFYING THE MOLECULAR STRUCTURE AT AND NEAR SAID SURFACE BY MOUNTING THE CRYSTAL IN PROXIMITY TO AN ANODE WITHIN A CHAMBER CONTAINING SAID AMODE AND A CATHODE; EVACUATING THE CHAMBER AND ESTABLISHING AN OXYGEN AMBIENT OF BETWEEN ABOUT 0.1 AND ABOUT 5.0 MILLIMETERS OF MERCURY PRESSURE THEREIN; APPLYING A PREDETERMINED LOW DIRECTCURRENT BIASING BETWEEN SAID ANODE AND CATHODE; CREATING AN OXYGEN ION PLASMS IN THE CRYSTAL AREA BY APPLYING MICROWAVE ENERGY TO THE CHAMBER AT SUCH A LOCATION, AT SUCH A SUFFICIENT VOLTAGE, AND AT HIGH ENOUGH FREQUENCY, AS TO CAUSE A PLASMA-FORMING GLOW DISCHARGE TO OCCUR IN THE CHAMBER SUCH THAT THE SURFACE OF THE CRYSTAL IS IN THE REGION OF THE DISCHARGE; AND ALLOWING THE PLASMA TO BOMBARD THE SURFACE FOR A PREDETERMINED TIME.
