Mix magnesium fluoride powder and high-purity PbF2 powder evenly, load the crucible clamp, put the crucible clamp on the crucible base, install the heating body, adjust the bottom of the crucible to make it in the high temperature zone, then install the insulation cover, seal the furnace and vacuum.
When the vacuum reaches 10-4 torr, heat at 500w power, dry for 1.5-2h, and then slowly raise the temperature at 1000W/15min. When the power reaches 6700W, keep the constant temperature for 45min, and then drop to 6400W for 45min.
At this time, the vacuum degree generally reaches 10-5 torr, and then the crucible is lowered at a speed of 4 mm/h for growth. After the crucible stops lowering, cool it at a rate of 150W/15min to room temperature, and then take out the magnesium fluoride crystal. The manufacturing process of magnesium fluoride is colorless crystal or powder, which is an important inorganic chemical raw material. Used as additive for electrolytic aluminum, flux for smelting magnesium, titanium In the production of aluminum, aluminum fluoride is used as an electrolytic bath component to reduce the melting point and improve the conductivity of the electrolyte. Used to inhibit fermentation in alcohol production Magnesium fluoride has a low refractive index and can form a wide band gap with high refractive index materials. It can be used as a low refractive index material in photonic crystals Mix magnesium fluoride powder and high-purity PbF2 powder evenly, load the crucible clamp, put the crucible clamp on the crucible base, install the heating body, and adjust the bottom of the crucible
