Embodiment 1

[0025] Take 0.58g of aluminum chloride and 0.3g of lithium sulfide powder, grind and disperse evenly, move them into a stainless steel reactor lined with a cylindrical corundum crucible, heat to 150°C, and keep warm for 3 hours. After the reaction is completed and cooled, pour the obtained solid powder into Put it into absolute ethanol, separate the solid and liquid after washing, and finally dry the solid at 80°C to obtain aluminum sulfide powder. figure 1 It is the XRD pattern of the reaction product of Example 1. There is only the XRD peak of LiCl in the reaction product, and no XRD peaks of other substances are observed. According to the type and number of atoms before and after the chemical reaction, there must be Al in the product. 2 S 3 produce. XRD picture as shown figure 1 shown.

Embodiment 2

[0027] Take 0.58g of aluminum chloride and 0.3g of lithium sulfide powder, grind and disperse evenly, move them into a stainless steel reactor lined with a cylindrical corundum crucible, heat to 400°C, and keep warm for 50h. After the reaction is completed and cooled, pour the obtained solid powder into Put it into absolute ethanol, separate the solid and liquid after washing, and finally dry the solid at 80°C to obtain aluminum sulfide powder.

Embodiment 3

[0029] Take 0.58g of aluminum chloride and 0.3g of lithium sulfide powder, grind and disperse evenly, move them into a stainless steel reactor lined with a cylindrical corundum crucible, heat to 300°C, and keep warm for 100h. After the reaction is completed and cooled, pour the obtained solid powder into Put it into absolute ethanol, separate the solid and liquid after washing, and finally dry the solid at 80°C to obtain aluminum sulfide powder.

Abstract

The invention discloses a synthesis method of aluminum sulfide, and belongs to the technical field of chemical synthesis. The method comprises the following steps: (1) weighing a certain amount of aluminum chloride and lithium sulfide; (2) uniformly mixing the above powders, transferring the uniformly mixed powder into a closed reactor and performing heating, and carrying out a constant temperature reaction for 1-100 h; and (3) separating a solid powder after the reaction to obtain aluminum sulfide. Compared with existing synthesis methods, the preparation method has simple synthesis process,mild reaction conditions, and relatively high purity of the synthesized aluminum sulfide.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a method for synthesizing aluminum sulfide. Background technique [0002] High-purity aluminum sulfide is often used as a fine chemical, pharmaceutical intermediate, material intermediate and semiconductor material. Already reported articles, Al 2 S 3 Combining with electrode materials such as graphene oxide can be used in energy storage devices, with good performance [Muhammad Faisal Iqbal, Mahmood-Ul-Hassan, et.al. 2 S 3 Nanorambutan for Supercapacitor Applications, Electrochimica Acta, 2017, 246, 1097-1103]. Will Li 2 S and Al 2 S 3 Powder mixing, through solid-phase sintering and high-energy ball milling, can also be made into solid electrolyte materials [Huang Fuqiang, a Li 2 S-Al 2 S 3 Solid electrolyte material and preparation method thereof. Shanghai: Shanghai Institute of Ceramics, Chinese Academy of Sciences, 2006]. At present, there ...
