PROCESS FOR CRYSTAL GROWTH OF KTIOPOŸ FROM SOLUTION

摘要

Process for crystal growth of KTiOPO4 from solution. Large flaw-free crystals of KTiOPO4 and the Rb, Ti and As analogs are produced by preparing a melt of KTiOPO4 or its analog in a flux in which the ratio by weight of KTiOPO4 to the flux at the seeding temperature is equal to the saturation value of the KTiOPO4 in the flux, suspending a crystal of KTiOPO4 in the melt and then slowly decreasing the temperature of the melt while essentially spatially isothermal conditions are provided throughout the melt.
