Embodiment 1
[0032] 1) Weigh the single substance of the raw material of the multi-component compound to be synthesized according to the proportion, and then put the simple substance that will not generate high vapor pressure during synthesis into the charging member of the charging device for the dual-temperature zone synthesis of the multi-component compound polycrystalline material bottom;
[0033]2) Connect the charging component loaded with the single substance to the quick conversion interface 11 of the vacuum sealing component with a three-way ventilation valve, and connect the quick conversion interface 11 to the backing vacuum pump 8 and the molecular pump through the three-way ventilation valve 6 After the air path between 4, open the front vacuum pump 8 for vacuuming, when the vacuum degree reaches 1×10 -1 After Pa, the gas path between the quick conversion interface 11 and the high-purity argon bag 9 is connected through the three-way gas exchange valve 6, and the high-purity a...
Embodiment 2
[0040] 1) Weigh the single substance of the raw material of the multi-component compound to be synthesized according to the proportion, and then put the simple substance that will not generate high vapor pressure during synthesis into the charging member of the charging device for the dual-temperature zone synthesis of the multi-component compound polycrystalline material bottom;
[0041] 2) Connect the charging component loaded with the single substance to the quick conversion interface 11 of the vacuum sealing component with a three-way ventilation valve, and connect the quick conversion interface 11 to the backing vacuum pump 8 and the molecular pump through the three-way ventilation valve 6 After the air path between 4, turn on the front vacuum pump 8 to vacuumize, when the vacuum degree reaches 3×10 -1 After Pa, the gas path between the quick conversion interface 11 and the high-purity argon bag 9 is connected through the three-way gas exchange valve 6, and the high-purit...
