GROWTH AND CHARACTERIZATION OF THE PEROVSKITE K1-YLIYTA1-XNBXO3CU

We report the growth of doped potassium lithium tantalate niobate (KLT N) crystals and characterization of their physical properties. The top seeded solution growth method is described. The specifics of a partic ular KLTN: Cu growth are presented, and the resultant crystal is descr ibed. The dielectric properties are compared to those of KTN; the addi tion of lithium is demonstrated to change the character of the phase t ransitions as well as increase the transition temperature. Phase diagr ams for the KLTN system are illustrated as a function of lithium and n iobium concentration.
