Single crystal growth of trivalent ion conducting aluminum tungstate-scandium tungstate solid solutions

A modified Czochralski (CZ) single crystal method was developed for the gro wth of aluminum tungstate-scandium tungstate solid solutions. The crystals were transparent and a satisfactory quality was ensured by polarizing micro scope measurements. Both Al and Sc were identified by electron probe microa nalysis (EPMA) measurements and the grown single crystals were identified t o be solid solutions. The trivalent Al/Se ion ratio in the single crystal s olid solutions was accurately determined from the lattice parameters calcul ated from X-ray powder diffraction analysis.
