Abstract
A method of manufacturing BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal wherein the BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal is grown by hydrothermal synthesis which applies heat and pressure to a nutrient composed of BaPb.sub.1-x Bi.sub.x O.sub.3 within a nitrate aqueous solution, such as LINO.sub.3, KNO.sub.3 and NaNO.sub.3 aqueous solutions.

A method of manufacturing BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal wherein the BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal is grown by hydrothermal synthesis which applies heat and pressure to a nutrient composed of BaPb.sub.1-x Bi.sub.x O.sub.3 within an aqueous solution containing a nitrate as the main component at a temperature and pressure effective to grow the BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal.
A method of manufacturing BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal comprising:
- providing a starting material comprised of BaCO.sub.3, PbO.sub.2 and Bi2O.sub.3 mixed together in the desired proportions;
- preparing a nutrient composed of BaPb.sub.1-x Bi.sub.x O.sub.3 polycrystalline from the starting material;
- and hydrothermally synthesizing the nutrient within a nitrate aqueous solution at a temperature and pressure effective to effect the growth of BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal.
A method of manufacturing BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal comprising:
- providing a nutrient composed of BaPb.sub.1-x Bi.sub.x O.sub.3 polycrystalline;
- and hydrothermally synthesizing the nutrient within a nitrate aqueous solution at a pressure and a nutrient temperature above 350.degree. C. to establish a temperature gradient within the nitrate aqueous solution effective to promote the growth of BaPb.sub.1-x Bi.sub.x O.sub.3 single crystal.
