Techniques and apparatus were developed to produce single crystals of LiF with selected ratios of the lithium isotopes containing not more than a few parts per million impurities. The starting material was prepared from purified aqueous solutions of LiOH and HF and was dehydrated in the molten state with anhydrous HF. The dehydrated LiF was then converted into a singie crystal in a unique Stockbarger furnace which has a window allowing visual monitoring of the crystal growth and variable electrical shunts making possible the application or removal of thermal gradients at will. Crystals weighing several hundred grams and containing 99.99, 98.06, and 96.50 at.% lithium-7 have been produced as part of a sequence which will include crystals do not display strain under polarized light and do not show OH/sup -/ absorption of infrared radiation. The purest crystals produced contain less than 1 ppm cationic impurities according to the results of emission spectroscopy and neutron activation analysis. (auth
