摘　　要：Sodium chlorate is a no coloured,no smell and no poisonous transparent crystal with the formula of NaClO 3.Its structure belongs to the cubic( T 23)class and exhibits optical activity.The space group is P 2 13 and there are four molecules per cubic unit cell with a =0.6570nm.We chose the crystal as a research system based on two reasons:(1)since the crystal structure belongs to the cubic class,the crystal faces,such as(100),(010),(001)are possessed of homogeneity,it is the suitable system for studying kinetics of crystal growth;(2)since the solubility of the NaClO 3 is higher in the H 2O and the crystal could be grown from low temperature solution,this is a suitable system for studying a influence of gravity on the boundary layer characteristics of the crystal growth under the microgravity condition.Sodium chlorate is a no coloured,no smell and no poisonous transparent crystal with the formula of NaClO 3.Its structure belongs to the cubic( T 23)class and exhibits optical activity.The space group is P 2 13 and there are four molecules per cubic unit cell with a =0.6570nm.We chose the crystal as a research system based on two reasons:(1)since the crystal structure belongs to the cubic class,the crystal faces,such as(100),(010),(001)are possessed of homogeneity,it is the suitable system for st...
