Production Method of Spherical graphite Powder :    

Spherical graphite is a new graphite material with important application value. The production method of spherical graphite will be introduced in detail below. There are two main production methods of spherical graphite: the chemical vapour deposition (CVD) method and the high-temperature pyrolysis method. 

Chemical vapour deposition (CVD) method 

The CVD method is an effective method to prepare high-performance spherical graphite. The main process includes the following steps: 

Firstly, natural graphite or artificial graphite raw materials are pyrolyzed at high temperatures to obtain pyrolytic graphite. 

Pyrolytic graphite was placed in a high-temperature cracking furnace, and a pyrolysis reaction was carried out under closed conditions to obtain pyrolysis products. 

The carbon atoms in the pyrolysis products were recrystallized into spherical graphite by chemical vapour deposition. 

Finally, the deposited spherical graphite was heat treated at a high temperature to obtain high-purity and high-quality spherical graphite products. 

High-temperature pyrolysis 

High-temperature pyrolysis is a traditional method for preparing spherical graphite, and its main process includes the following steps: 

The raw materials of natural graphite or artificial graphite are pre-treated by crushing, screening and drying; 

The pre-treated graphite raw material was placed in a high-temperature cracking furnace, and the cracking reaction was carried out under closed conditions to obtain the cracking product. 

The carbon atoms in the pyrolysis products were recrystallized into spherical graphite by heat treatment at high temperatures. 

Finally, the surface treatment of the spherical graphite obtained by heat treatment is carried out to obtain high-quality spherical graphite products. 

High-temperature pyrolysis equipment is relatively simple, has low energy consumption, and can prepare large graphite products. However, this process is susceptible to being affected by variables like the raw material's properties and the temperature at which cracks are formed, and the purity and quality of the product are not stable enough. 

In addition to the two main production methods, there are electrochemical methods, ion implantation methods and other methods for preparing spherical graphite. The properties and characteristics of spherical graphite obtained by different preparation methods are also different.
