Benefits of technology

This new technology uses easy operations and no harmful chemical substances like chlorine gas for extraction of pure metallic Magnesum (Mg). It produces Mg at an even better level compared to previous methods that were used beforehand. Its technical effect will be improved efficiency, safety, reliability during production processes while minimizing environmental impact on workers' health.

Problems solved by technology

This patented technical problem addressed in the patents relating to producing pure magnetically active material from molten salt involves removing unwanted substances like oxygen (oxygen) during melting processes while maintaining their purification level at least upwards of 899.9%.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the examples, but not as a limitation to the present invention.

[0021] Embodiments of the invention. A preparation method of high-purity magnesium. Such as figure 1 shown. A preparation method of high-purity magnesium. The method uses magnesium ingot 12 as a raw material to produce high-purity magnesium with a purity equal to or higher than 99.98%; the steps are as follows:

[0022] a), the φ 300 * 130mm magnesium ingots placed in the graphite crucible 14 are divided into three layers and 5 pieces per layer are placed in the vacuum distiller 4, and an aluminum plate 13 is placed on each layer of magnesium ingots; then the vacuum distiller is put into a vacuum Distillation furnace 1;

[0023] b), vacuumizing between the vacuum distiller 4 and the condenser 9 and between the vacuum distiller 4 and the vacuum distillation furnace 1;

[0024] c), heating the vacuum distillation furna...

Abstract

The invention discloses a method and a device for preparing high-purity magnesium. The method is to use magnesium ingot as a raw material to produce the high-purity magnesium with the purity of 99.98 percent. The device comprises a vacuum distilling furnace (1), an inner wall of the vacuum distilling furnace is provided with a heating element (2), and the vacuum distilling furnace is provided with a vacuumizing interface (3); the inside of the vacuum distilling furnace is provided with a vacuum distiller (4), the upper side of the vacuum distiller is provided with an annular water jacket (5), and the annular water jacket is provided with a circulating water interface (6); the upper side of the vacuum distiller is provided with a large flange (7), the large flange is provided with an annular water jacket (8), and the annular water jacket is provided with the circulating water interface; and the large flange is provided with the vacuumizing interface and a condenser (9). The method improves the high-purity magnesium with the purity up to 99.98 percent by using the apparatus with simple operation and no pollution so as to meet the requirements on development of national defense industry technology and nuclear industry technology. The device has the advantages of long service life, simple structure, less investment in the apparatus, and safe and reliable use.
