Abstract : A low aging piezoelectric resonator is made from a plate of piezoelectric material using standard resonator fabrication techniques with identical electrodes applied to both major faces of the plate; the electroded plate mounted in a suitable enclosure and the unit vacuum baked and sealed under high vacuum to remove as much contamination as possible, and a DC voltage impressed between the resonator electrodes and the enclosure to create a static electric filed within the enclosure.
