Crucible for preparing elemental two-dimensional material and other composite materials

Abstract

The invention discloses a crucible for preparing an elemental two-dimensional material and other composite materials, and relates to the technical field of new material preparation. The crucible for preparing the elemental two-dimensional material and the other composite materials is characterized in that a gas distribution box (9) is arranged below a crucible body (4), exhaust holes in the gas distribution box are connected with vent holes (7) formed in the bottom of the crucible body, so that the gas distribution box is not in a metal solution, then the situation that gas is cracked in the gas distribution box to generate graphene or other elemental carbon and the like can be effectively prevented, furthermore, the cooling effect is improved, the gas distribution box is arranged in a cooling mechanism, and then cooling gas is introduced into the cooling mechanism to cool the gas distribution box so that the gas distribution box can be better cooled, the situation that the gas is cracked in the gas distribution box to generate the graphene or the other elemental carbon and the like is prevented, meanwhile, the phenomenon that the vent holes are blocked can be further prevented, and the crucible has the characteristics of being simple in structure, good in using effect and the like, and is suitable for wide-range popularization and application.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of preparation of new materials, in particular to a crucible for preparing simple two-dimensional materials and other composite materials. [0003] 【Background technique】 [0004] It is known that simple two-dimensional materials and composite materials play a very important role in the development of modern science and technology. The research depth and application breadth of simple two-dimensional materials and composite materials, as well as the speed and scale of production development, have become one of the important symbols to measure the advanced level of a country's science and technology. Since the beginning of the 21st century, the global market for simple two-dimensional materials and composite materials has grown rapidly, especially in Asia, especially in China. Among them, the common composite materials are silicon-coated carbon composite materials, carbon-coated silicon composite mate...
