About Strontium Chloride

Strontium Chloride is an important inorganic chemical product, mainly used in the production of magnesium-strontium alloy, high-purity strontium salt, high-grade magnetic materials, and is also widely used in TFT-LCD liquid crystal, PDP plasma color TV and medicine, and has a high This article takes the key step in the preparation process of strontium chloride-the cooling crystallization process of SrCl2 6H2O as the object, carries out the crystallization metastable zone and nucleation process, crystallization process optimization, numerical simulation and control of the crystallization process, and crystal morphology control Theoretical and technological research provides theoretical guidance for industrial production. The research results show that the increase in saturation temperature significantly shortens the induction period of SrCl2 6H2O crystallization and narrows the metastable zone.

The increase in temperature reduction rate shortens the induction period and widens the metastable zone. Increasing the stirring rate helps to nucleate, shorten the induction period and narrow the metastable zone. The presence of impurity Ca2+ shortens the induction period and narrows the metastable zone. Small-sized seed crystals have a larger surface area and can effectively adsorb the nucleation group In order to prepare SrCl2·6H2O crystals with large size and concentrated distribution, the initial supersaturation should be controlled to 1.150~1.250, and the cooling rate should be 15.0~ 20℃·h-1, stirring speed 400~500 rpm, crystal growth time 5-10 min, SrCl2·6H2O crystals obtained in this process range are rod-shaped, average length Lmean is 1206.78μm, average width Wmean is 80.06 μm .

The coefficient of variation CVL and CVW are 0.2372 and 0.2079, respectively. Adding an appropriate amount of small-sized seed crystals can reduce the crystal size distribution range, but at the same time the crystal size is also reduced. Further research using the response surface method shows that the initial supersaturation is the influence The key factors of crystal size, cooling rate and crystal growth time are the key factors of crystal size distribution.
