II. Materials and equipment
1. Materials: praseodymium element, sodium hydroxide, oxygen, etc.
2. Equipment: reactor, stirrer, heater, cooler, filter, etc.
3. Manufacturing steps
1. Dosing: add praseodymium element, sodium hydroxide and other raw materials into the reactor according to a certain proportion.
2. Stirring and heating: Start the stirrer and heat the reactor at the same time, so that the raw materials are fully mixed and heated to a certain temperature.
3. Oxygen Reaction: Oxygen is passed into the reactor to make praseodymium react with oxygen to produce praseodymium oxide.
4. Cooling and Filtration: After the reaction is completed, the material in the reactor is cooled, and then the praseodymium oxide is separated from the impurities through a filter.
5. Washing and drying: Wash the praseodymium oxide with deionized water to remove the impurities on the surface, and then dry it to get the finished praseodymium oxide. Precautions
1. Control the reaction temperature: The reaction temperature has an important effect on the generation of praseodymium oxide, so the reaction temperature should be strictly controlled within the appropriate range.
2. Adjustment of pH value: Adjusting the pH value of the reaction system is conducive to the generation of praseodymium oxide and the removal of impurities.
3. Preventing the mixing of impurities: In the manufacturing process, the mixing of impurities should be avoided as much as possible to ensure the product quality.
