Lanthanum oxide manufacturing method
1. Introduction
Lanthanum oxide is an important chemical production raw material, widely used in catalysts, phosphors, glass, ceramics and other fields. With the continuous development of science and technology, the manufacturing method of lanthanum oxide is constantly improving and optimizing. This article will introduce a common lanthanum oxide manufacturing method.
2. materials and equipment
1. Materials: lanthanum chloride, sodium hydroxide, deionized water, etc.
2. Equipment: reaction kettle, stirrer, filter, oven, etc.
3. manufacturing steps
1 ingredients: according to a certain proportion of lanthanum chloride, sodium hydroxide and deionized water into the reaction kettle.
2. Stirring: Turn on the stirrer to mix the reactants thoroughly.
3. Reaction: At a certain temperature, the reactants are fully reacted to generate lanthanum oxide precipitate.
4. Filtration: The lanthanum oxide precipitate is separated from the mother liquor by means of a filter.
5. Washing: The lanthanum oxide precipitate was washed with deionized water to remove surface impurities.
6. Drying: The washed lanthanum oxide precipitate is placed in an oven and dried at a certain temperature.
7. Pulverization: The dried lanthanum oxide precipitate is pulverized to a powder of the desired particle size.
4. precautions
1. Control the reaction temperature and time to ensure that the reaction is complete.
2. when washing to fully remove surface impurities, to ensure product quality.
3. Control the temperature and time during the drying process to prevent product agglomeration.
4. When crushing, choose the appropriate equipment to ensure uniform product size.
5. quality inspection
After the
is manufactured, the quality of lanthanum oxide needs to be tested, including purity, particle size, chemical properties, etc. Ensure product quality meets relevant standards and requirements.
6. environmental protection and safety
In the manufacturing process of lanthanum oxide, we must pay attention to environmental protection and safety. Take effective measures to reduce the discharge of waste gas, waste water and solid waste, and reduce the impact on the environment. At the same time, strengthen equipment maintenance and operation specifications to ensure safety in the production process.
7. conclusion
lanthanum oxide as an important raw material for chemical production, its manufacturing method is continuously improved and optimized. By controlling the reaction conditions, washing, drying and pulverization, high-quality lanthanum oxide can be produced. In the production process, we should pay attention to environmental protection and safety, and take effective measures to reduce the impact on the environment.
