The Czochralski method of pulling from the melt has been applied to the growth of single crystals of divalent fluorides of Ca, Sr, Ba, Co, and Mn, and the compound KMnF3. The trivalent rare earth ions Ce, Nd, Sm, Eu, Gd, Tb, and Yb were introduced into CaF2and the distribution coefficient was determined to be close to unity in all cases.
