Zirconium oxychloride is a basic zirconium compound product which is widely used. Its production process is mainly caustic soda method, lime method, and chlorination method. The caustic soda method and the lime method can be collectively referred to as the alkali solution method. The caustic soda method has been improved from the two-acid and two-alkali method to the one-acid-alkali method, and the chlorination method is divided into the boiling chlorination method and the carbonation chloride method. Due to the different methods used in the crystallization process, it can be divided into mechanical crystallization products and natural crystallization products; quality characteristics, and applicable fields.
