Abstract:
     The present invention relates to a method for growing crystal by smelting salt crystallon. The low temp. phase-deviation barium borate monocrystal grown with this method is proved to be a good non linear optical, thermoelectric etc. multi-functional material. Its developing method contains three steps: material mixing, crystallon putting in and growing. Na2O or NaF is adopted as an auxiliary flux; the crystallon is placed at the surface of the melted liq.. The orientation of crystallon is in the direction of C-axis. The crystallon grows with a speed of 0.03 deg.C per hour to 0.2 deg.C per hour. With this method, standing bowl shaped big monocrystal with a dia. of 67 mm and a central depth up to 15 mm can be prepd. steadily.
