Industrial grade lanthanum hydroxide, CAS number 14507-19-8, is an important inorganic compound. It has a wide range of applications in many fields, especially in materials science, energy technology, environmental protection, and catalyst preparation. This article will detail the properties, preparation methods, application fields and market prospects of industrial-grade lanthanum hydroxide.
1. Properties of industrial-grade lanthanum hydroxide.
Industrial grade lanthanum hydroxide is a white or light greenish amorphous powder with a high degree of hygroscopicity. It has less solubility in water but higher solubility in alkaline solutions. In addition, lanthanum hydroxide also has good thermal and chemical stability, and can remain stable at high temperatures and strong acids and alkalis.
2. Preparation method of industrial-grade lanthanum hydroxide.
There are two main preparation methods for industrial-grade lanthanum hydroxide: direct precipitation and metathesis. The direct precipitation method is to react the lanthanum salt solution with the alkaline solution to generate a lanthanum hydroxide precipitate, and then go through filtration, washing, drying and other steps to obtain the product. The metathesis method is to use lanthanum hydroxide and other salts to metacompose to generate lanthanum hydroxide. Both methods have their own advantages and disadvantages, and the choice depends on factors such as production scale, raw materials**, and product quality requirements.
3. Application fields of industrial-grade lanthanum hydroxide.
1.Materials science: Industrial-grade lanthanum hydroxide is an important raw material for the preparation of lanthanide oxides, lanthanide compounds and other lanthanide functional materials. These materials have a wide range of applications in the fields of electronics, magnetism, optics and catalysis. For example, lanthanide oxides can be used as efficient catalysts in petrochemical, environmental protection and other fields.
2.Energy technology: Lanthanum hydroxide plays an important role in new energy technologies such as solar cells and fuel cells. It can be used as an electrode material to improve the energy density and cycle life of the battery. In addition, lanthanum hydroxide can also be used to prepare energy storage materials, such as supercapacitors.
3.Environmental protection field: industrial-grade lanthanum hydroxide has good adsorption performance and ion exchange performance, and can be used in wastewater treatment, heavy metal ions** and other fields. It can effectively remove heavy metal ions and other harmful substances in wastewater and protect the environment and water resources.
4.Catalyst preparation: Lanthanum hydroxide can be used as a catalyst carrier or additive to improve the activity and selectivity of the catalyst. In the fields of petrochemical industry, ammonia synthesis, hydrogen production, etc., lanthanum hydroxide catalyst has a good application prospect.
