TGS crystal growth polymorphism and surface diffusion growth mechanism

Four faces of TGS crystal were chosen to study the growth kinetics. BCF spi ral growth mechanism for the surface diffusion model was analyzed using the kinetic data of the four faces. We found it is more important that the gro wth units enter the surface layer to grow after overcoming the dehydration activation energy, than the process of surface diffusion. Two simple crysta l forms of TGS spontaneous nucleation crystals were also observed.
