Basic properties of graphite blocks
1.Structural features
Graphite block is composed of countless graphite sheets arranged in parallel, and each graphite sheet is composed of a ring structure composed of six carbon atoms. These parallel-arranged graphite sheets are attracted to each other through van der Waals forces to form a layered structure.
2.physical properties
Graphite blocks have high thermal and chemical stability and are not easily corroded and eroded. At the same time, graphite block also has good electrical conductivity and thermal conductivity, and is an ideal conductive material.
3.Mechanical properties
Graphite block has high strength, high hardness, high toughness and good impact resistance, making it an ideal structural material. In addition, graphite blocks also have good wear resistance and fatigue resistance.
Preparation method of graphite block
1.high temperature pyrolysis
High temperature pyrolysis is a common method for preparing graphite blocks. This method requires pyrolysis of raw materials at high temperatures to generate graphite blocks.
2.chemical vapor deposition
Chemical vapor deposition is a method that uses heat and physical conditions generated by chemical reactions to prepare graphite blocks.
3.mechanical compression method
Mechanical compression method is a method of preparing graphite blocks through mechanical action. This method requires mechanical compression of graphite powder to produce graphite blocks.
