Method for preparing elemental materials by reduction of single-atom carbon

Abstract

The invention belongs to the field of materials, and relates to a method for preparing elemental materials by reducing single-atom carbon. The method includes: in the melt medium, at 300°C to 1500°C, the organic carbon source is cracked into atomic carbon and dissolved in the melt medium, and the atomic carbon is oxidized with the elemental precursor compound placed in the melt medium In the reduction reaction, the precursor compound is reduced to an element, and the element is supersaturated and crystallized in the melt medium to obtain an element material. The method of the invention can prepare high-quality, self-crystallized single substance materials at a lower temperature and at a lower cost.

Description

technical field

[0001] The invention relates to the field of materials, in particular to a method for preparing elemental materials by reducing single-atom carbon. Background technique

[0002] Elemental materials include metals and nonmetals. Elemental materials, as special functional materials and structural materials, are the basic materials of various high-end manufacturing industries. The products are widely used in high-tech fields such as aviation, aerospace, shipbuilding, nuclear industry, electronics, automobiles, and new energy. However, substances in nature rarely exist in the form of simple substances, and mostly exist in the form of compounds such as oxides, carbides, nitrides, sulfides, and various acid salts. Therefore, it is necessary to reduce the compounds to obtain simple substances. The most important methods are thermal reduction and electrolysis. Among them, metallothermal methods such as carbothermal method, silicothermal method, aluminothermic metho...
