  • Relaxor-PT ferroelectric single crystals
    Patent number: 8241519
    Abstract: A <110> domain engineered relaxor-PT single crystals having a dielectric loss of about 0.2%, a high electromechanical coupling factor greater than about 85%, and high mechanical quality factor greater than about 500 is disclosed. In one embodiment, the relaxor-PT material has the general formula, Pb(B1B2)O3—Pb(B3)O3, where B1 may be one ion or combination of Mg2+, Zn2+, Ni2+, Sc3+, In3+, Yb3+, B2 may be one ion or combination of Nb5+, Ta5+, W6+, and B3 may be Ti4+ or combination of Ti4+ with Zr4+ and/or Hf4+.
