Spherical Graphite C Powder CAS 7782-42-5

About Spherical Graphite Powder:
The appearance of spherical graphite is similar to that of ordinary graphite, showing as a black solid powder. However, its shape is closer to spherical than flake or granular. The size of spherical graphite is usually between tens of nanometers and hundreds of microns, with a narrow size distribution. 
Regarding physical properties, spherical graphite has the characteristics of high crystallinity, high electrical conductivity, and high thermal conductivity. Its crystal structure consists of hexagonal carbon rings, which can efficiently conduct electron and heat conduction. In addition, spherical graphite also has high hardness and good chemical stability and can be used in high-temperature and corrosive environments. Regarding chemical properties, spherical graphite has low oxygen and sulfide content and strong oxidation and corrosion resistance. Because its surface is rich in active groups, spherical graphite has good interfacial properties and chemical reactivity.

Application of Spherical Graphite Powder :   

Spherical graphite is a novel kind of graphite that offers a variety of applications because of its unique physical and chemical characteristics. Some of the main application areas of spherical graphite are described in detail below: 

Battery field: Spherical graphite is important in manufacturing and can be used as a negative electrode and capacitor material. Because the spherical graphite has high conductivity and chemical stability, It will improve the energy density, capacity, and efficiency of discharge and charge and the battery's longevity. Spherical graphite batteries have broad application prospects in e, electric vehicles and other fields. 

In the field of refractories, spherical graphite has high thermal conductivity and oxidation resistance and can be used as an additive for refractories. Adding it to refractory materials can improve the high-temperature resistance, corrosion resistance, and service life of the material. Spherical graphite refractories are widely used in high-temperature industries such as steel, glass, and ceramics. 

Lubricant field: Spherical graphite has excellent lubricating properties and chemical stability and can be used as a lubricant additive. Adding to lubricants can improve lubrication, wear resistance, and corrosion resistance. Spherical graphite lubricants are widely used in machinery manufacturing, automobile maintenance, aerospace, and other fields. 

Catalyst carrier: Spherical graphite has high thermal conductivity and a specific surface area, which can be used as a catalyst carrier. Utilizing it as a support material may increase the catalyst's performance, selectivity, and durability. Spherical graphite catalyst carrier has important applications in the petrochemical industry and environmental protection. 

Electromagnetic shielding material: Spherical graphite exhibits excellent electrical conductivity and a large specific surface area. It is a suitable electromagnetic shielding material. An electromagnetic shielding layer can be formed when added to coatings or plastics, effectively reducing electromagnetic interference and radiation. Spherical graphite electromagnetic shielding materials are important in electronic equipment, aerospace, and military fields. 

Biomedical field: Spherical graphite has good biocompatibility and non-toxicity and can be applied to the biomedical field. For example, it can be used as a drug carrier for drug delivery and treatment of diseases such as tumors. In addition, spherical graphite can also be used as a biosensor and biological imaging agent.

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 vapor deposition (CVD) method and the high-temperature pyrolysis method. 

Chemical vapor 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 vapor 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.
