Abstract
Large flow-free crystals of KiTiOPO.sub.4 and the Rb, Tl, and As analogs are produced by preparing a melt of KtiOPO.sub.4 or its analog in a flux in which the ratio by weight of KTiOPO.sub.4 to the flux at the seeding temperature is equal to the saturation value of the KTiOPO.sub.4 in the flux, suspending a crytal of KTiOPO.sub.4 in the melt and then slowly decreasing the temperature of the melt while essentially spatially isothermal conditions are provided throughout the melt.
