  • Method of making ternary piezoelectric crystals
    Patent number: 8597535
    Abstract: A ternary single crystal relaxor piezoelectric of PMN-PZ-PT grown from a novel melt using the Vertical Bridgeman method. The ternary single crystals are characterized by a Curie temperature, Tc, of at least 150° C. and a rhombohedral to tetragonal phase transition temperature, Trt, of at least about 110° C. The ternary crystals further exhibit a piezoelectric coefficient, d33, in the range of at least about 1200-2000 pC/N.

  • Single crystal scintillator materials and methods for making the same
    Patent number: 7520931
    Abstract: A method of making a single crystal material is provided. The method includes providing a polycrystalline material having a plurality of grains. The method further includes adding a seed crystal to the polycrystalline material to define a plane of growth for the polycrystalline material. Further, the polycrystalline material having the seed crystal may be subjected to heat-treating, where the heat-treating does not include melting the polycrystalline material.

  • Micromachined imaging transducer
    Publication number: 20070038111
    Abstract: The present invention generally relates to medical devices, and more particularly to an improved medical imaging device. In one embodiment, an imaging device includes a drive shaft having proximal and distal ends received within the lumen; and an imaging transducer assembly coupled to the distal end of the drive shaft and positioned at the distal portion of the elongate member. The imaging transducer assembly includes one or more imaging transducers formed with a piezoelectric composite plate using photolithography based micromachining.

  • Method for reduction of sinter temperatures of antiferroelectric, lead-based ceramics by use of lithium compound additions and capacitors made with such ceramics
    Patent number: 5993895
    Abstract: A method for densifying a dielectric antiferroelectric material includes the steps of adding a compound which includes lithium to the dielectric material to create a mixture thereof. Thereafter, the mixture is heated to a temperature of not greater than about 1100.degree. C. for a predetermined period to densify the mixture. It is preferred that the lithium compound be a lithium salt and that the dielectric material comprise a PLZT composition.
