There are some factors which will be influenced to grow a crystal, these are temperature, vapour pressure, super saturation of solution and stimulation of crystallization. This paper gives the microphotographs of Rochelle salt and Di-kalium tartrate (DKT) crystals which are growing in these conditions. From the observation of microphotographs, I conclude as follows, for the DKT crystal growth, find the different habits between the repose and the agitative crystallizations, the crystal takes form of a radial crystal in the former case, in the other hand, it takes form of a native DKT crystal in the latter. But for the Rochelle salt crystal growth, I don't find the difference between two cases, at 50℃, Rochelle salt decomposes its crystallization. The rate of advance of a growth is proportional to the temperature.
