Abstract
A method of producing large flow-free single crystals of either LiNdP.sub.4 O.sub.12 or XB.sub.2 O.sub.4, where X is Ba, Sr or Ca, comprising the steps of, preparing a mixture of the final product and a flux of oxide of their precursors, melting the mixture, fluxing at a temperature substantially equal to the saturation value then suspending a seed in the melt, and cooling while maintaining essentially spatially isothermal conditions throughout said melt to crystallize single crystals on the seed.
