The results of the effect of the growth history on KDP crystals growth mechanism are presented in the paper. Crystals were grown in temperature range of 24-28°C, from aqueous solutions saturated at To=(31.0±0.1)°C. Two types of experiments were performed. In both types, after the nucleation at Tn=(26.0±0.1)°C crystals were grown at the same temperature for about 1.5 h and then disolved at Td=(34.0±0.1)°C for about 15 min. After refaceting, in the first type, the crystal growth started at 24°C, followed by the temperature increasing in steps of ΔT=1°C to 28°C. In the second type, after refaceting the crystal growth started at 28°C, followed by the temperature decreasing in steps of ΔT=1°C to 24°C. Obtained results indicate that KDP crystals growth mechanisms do not depend on growth history. They are discussed in accordance with the current theories.
