The neutralization of copper chloride solution with ammonia water immediately produces a large amount of slurry-like common Basic Copper Chloride. The basic copper chloride crystal nucleus can be generated by coordination catalytic liquid phase precipitation method. Under appropriate conditions, the nucleation rate can be controlled and the crystal growth speed can be accelerated. The crystal nucleus can continue to grow, and the growth particle size is proportional to time.

The suitable pH value for crystallization and growth of Basic Copper Carbonate is 5.0-5.5, and the temperature is 70-80℃.  In addition to pH value and temperature being the key factors, the reaction influencing factors are also closely related to conditions such as stirring speed, stirring mode, catalyst concentration, crystallizer structure, feeding speed and mode.
