Embodiment 1
[0028] Weigh 150 grams of commercially available reagent grade Mg(OH) 2 To prepare a solution, weigh 150 grams of commercially available reagent grade oxalic acid to prepare a solution. The reactor containing the magnesium hydroxide solution is placed on a magnetic stirrer and stirred with an external ultrasonic wave instrument, the frequency is 21KHz, and the output power is 0.8KW. Add oxalic acid solution dropwise to generate magnesium oxalate. The water in the reaction liquid was evaporated and filtered to obtain fine particle crystals of magnesium oxalate. After drying the magnesium oxalate fine particle crystals in a horse temperature furnace, place the magnesium oxalate fine particle crystals in a high-purity quartz glass tube, cover both ends with high-purity graphite, and then place them in the horse temperature furnace To obtain a mixture of metal magnesium powder and carbon dioxide gas, and gas-solid separation to obtain magnesium powder. Magnesium powder particles ...

Embodiment 3
[0032] Weigh 150 grams of commercially available reagent grade Mg(OH) 2 Prepare a 5% solution, weigh 150 grams of commercially available reagent grade oxalic acid to prepare a 5% solution. The reactor containing the magnesium hydroxide solution was placed on a magnetic stirrer and stirred at a stirring rate of 3000 revolutions per minute. The external ultrasound device has a frequency of 130KHz and an output power of 0.8KW. Add oxalic acid solution dropwise to generate magnesium oxalate. The water in the reaction liquid was evaporated and filtered to obtain fine particle crystals of magnesium oxalate. After drying the magnesium oxalate fine particle crystals at 90℃ in a horse temperature furnace, place the magnesium oxalate fine particle crystals in a high-purity quartz glass tube, cover both ends with high-purity graphite, and then place them in the horse temperature furnace For high-temperature gasification, the high-temperature gasification temperature is 550°C, and the hi...
