Explosion impact synthetic method of beta-C3N4

Abstract

The invention relates to a synthetic processing method of ultrahard material, in particular to a Beta-C3N4 ultrahard material explosive shock synthetic method which solves the problem of processing and manufacturing C-N ultrahard material. The invention is characterized in that explosive and reaction precursor are arranged in a sealed container and then the explosive is ignited to cause explosionso as to obtain detonation products; finally, the detonation products is treated with purification processing to obtain the Beta-C3N4 ultrahard material. The invention has the beneficial effects thatthe method of the invention can prepare a carbonitride compound by synthesis and is practicable; compared with the methods which are listed in the background technology, the method has the advantagesof simple operation, short reaction process and convenient purification, etc.

Description

technical field The invention relates to a method for synthesizing and processing superhard materials, specifically a kind of β-C 3 N 4 Explosive Shock Synthesis of Superhard Materials. Background technique At present, hard materials widely used in (processing and manufacturing fields) include titanium nitride and diamond. Diamond has extremely high hardness. Diamond comes from natural minerals or man-made. Natural diamond is rare and precious. Therefore, artificial diamond is commonly used in the processing and manufacturing industry. Its preparation process is complicated, it is easy to react with iron-based alloys, and its thermal stability is extremely high. Poor, not only expensive, but also can not be used to cut steel, when the temperature of diamond in the air exceeds 700 ℃, it will generate carbon dioxide. Therefore, in the industrial sector, especially in the processing of high-precision non-heavy tools such as gear hobbing cutters and gear shaper cutters for pr...
