A synthetic method for lanthanum hydroxychloride suitable for industrialization and its thermal decomposition properties.

ABSTRACT: A reactive crystallization method for the synthesis of lanthanum hydroxychloride (La(OH)₂Cl) was developed to provide a new low-carbon route for the purification of rare earth elements in hydrometallurgy. The synthetic method reported herein represents a unique low-temperature route, short preparation time and inexpensive materials compared with previous methods, thus making it promising for industrial applications. The key factors controlling the product's phase were determined using single factor tests involving temperature, concentration of NH₄Cl in the base solution and the molar ratio of NH₄OH/La³⁺ added per minute into the base solution. Otherwise, the outcome is lanthanum hydroxide (La(OH)₃). Subsequently, the synthesized produc
