SCDD (Silicon Carbide Derived Diamond) and CDC (Carbide Derived Carbon) preparation device

Abstract

The invention discloses an SCDD (Silicon Carbide Derived Diamond) and CDC (Carbide Derived Carbon) preparation device. The preparation device comprises a base (2) and a plunger (12), wherein the plunger (12) is arranged on the base (2) to form a vacuum protective chamber (30). The SCDD and CDC preparation device is characterized in that a reaction pipe (13) is arranged in the vacuum protective chamber (30), an operating platform (15) for placing a reaction test sample is arranged in the reaction pipe (13), a metal sleeve (11) is sleeved on a position outside the reaction pipe (3), corresponding to the operating platform (15) and an inductive heating coil (25) is sleeved on the metal sleeve (11); either one or two ends of the reaction pipe (13) are further sleeved with a cooling seat (10), the cooling seat (10) is connected with a cooling pipe (5) leading to the outer part of the vacuum protective chamber, and the cooling pipe (5) is used for connecting with a cooling device or a cold source. The SCDD and CDC preparation device is simple in structure, high in safety factor, adjustable in heating position, durable and stable to heat, unlikely to damage, convenient to install and maintain, and convenient for experimental recording and analysis; and the gas-solid reaction inside the device is complete, so that CDC and SCDD materials with better qualities can be prepared.

Description

technical field [0001] The invention relates to a gas-solid reaction generating device, in particular to a device for etching carbides to prepare carbon materials, in particular to a device for preparing SCDD and CDC. Background technique [0002] As we all know, carbon is abundant in nature, and "carbon materials" have many properties that can be used by people. In recent years, the application of "carbon materials" has become more and more extensive. The preparation process and equipment of various "carbon materials" have always been a research hotspot, and human beings may enter the "carbon material era". CDC (carbide derived carbon carbide derived carbon) and SCDD (silicon carbide derived diamond carbide derived diamond) are two relatively new "carbon materials", which have only attracted people's attention in recent years. There are not many research documents, and domestic related research has not yet started. As a new porous carbon material, CDC material has great p...

Problems solved by technology

[0004] The purpose of the present invention is to design a kind of "carbon material" that can realize stable and long-term continuous heating reaction to prepare "carbon material" due to the lack of suitable CDC and SCDD manufacturing devices, which has a high safety factor and relatively high reaction efficiency. High, simple structure, easy to use and maintain, easy to adjust, record and analyze CDC and SCDD preparation devices, in order to prepare CDC and SCDD materials with better quality, and provide a hardware basis for further research on this process
