Preparation of Cerium Fluoride CeF3 from China
Cerium Fluoride CeF3 from China is cheaper than other rare earth products, making it the first rare earth with practical use. Storage method should be stored in a cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. The packaging should be airtight and must not come into contact with air. It should be stored separately from oxidants and edible chemicals, and should not be mixed. Use explosion-proof lighting and ventilation. Prohibit the use of mechanical equipment and tools that are prone to sparks. Storage areas should be equipped with emergency release equipment.
70 g of carbon trichloride and cerium are mixed in an inert gas and placed in a graduated cylinder or pressed into a graduated cylinder with a power press. Glycerin comes with a perforated button cover for ventilation and is placed in a closed magnesia. Then put in the quartz tube. One end of the 55/a is welded to the tapered joint and the other end is welded to the ground. The quartz tube was sealed with paraffin in a 0.133pa vacuum system.
The reaction occurs when heated to 550-600°C in a 6kW induction furnace. After 5 minutes, the temperature reaches 1000 °C, and the temperature is kept for 13 minutes, and the rare earth metals are completely agglomerated. After cooling to room temperature, the CaCl2 and Ca were removed by soaking the button with water, and the molten block of Cerium Fluoride CeF3 from China stayed at the bottom.
