Physical and chemical indicators of graphite materials :Chemical properties

Chemical properties of carbon graphite materials: Carbon graphite materials are chemically stable and therefore a corrosion resistant material. However, under certain conditions, carbon also interacts with other substances. The main reactions are: oxidation at high temperatures with oxidizing gases or in strong oxidizing acids; melting at high temperatures to form metals and forming carbides, Interlayer…

Physical and chemical indicators of graphite materials :Thermal properties

Thermal properties of graphite materials: The thermal properties of solid materials are essentially the performance of lattice thermal vibrations in all respects. The specific heat capacity, thermal expansion, and heat transfer of solid materials are directly related to this. The thermal properties of graphite materials include heat capacity, entropy, vapor pressure, thermal conductivity, thermal expansion…

Physical and chemical indicators of graphite materials :Mechanical mechanics

The main indicators of mechanical properties of graphite materials are mechanical strength, elastic modulus, creep, and friction properties, etc. A. The mechanical strength of graphite materials is compressive strength, flexural strength, tensile strength, etc. Mechanical strength is the ultimate resistance of materials against external damage. Compressive strength is the moment when the material is crushed…

Physical and chemical indicators of graphite materials :Structural

A. Bulk density Bulk density is a physical quantity that characterizes the macroscopic structure of a material. The higher the bulk density, the denser the macroscopic structure of the material, and the lower the bulk density, the looser the macroscopic structure of the material. Calculation formula: bulk density = mass / volume The unit of…
