Abstract
A hydrothermal process is disclosed for growing a crystal at MTiOXO.sub.4 wherein M is NH.sub.4, K, Rb and/or Tl or mixtures thereof with Cs and X is P and/or As, at elevated temperatures using a mineralizer comprising both M.sup.+1 and X.sup.+5 and an amount of F.sup.-0 effective to increase the solubility of MTiOXO.sub.4 in the mineralizer. Mineralizers containing F.sup.-1, M.sup.+1 and X.sup.+5 are disclosed wherein F.sup.-1 is present in an amount effective to increase the solubility of MTiOXO.sub.4 in the mineralizer and to provide a MTiOXO.sub.4 solubility of at least about 1% by weight at the operating temperature and pressure for the hydrothermal production.
