PURPOSE:To produce the titled single crystal without any impurities, variations in composition X, and internal strains and which can be treated at a comparatively low temp. by growing a crystal by the hydrothermal synthesis at specified temp. and pressure in an aq. soln. consisting essentially of nitrates. CONSTITUTION:A starting material and a substrate for growth are set in an autoclave filled with an aq. soln. consisting essentially of nitrates (e.g., LiNO3, KNO3, NaNO3, etc.), and the BaPb1-xBixO3 single crystal is grown by the hydrothermal synthesis at necessary temp. and pressure. The growth can be carried out by this method at about 300-600 deg.C, which are fairly low as compared with the conventional technique. Consequently, the titled single crystal without any impurities, variations in composition X, and internal strains can be produced. |
