Properties and applications of isotropic flake graphite

Properties and Applications of isotropic flake graphite

Isotropic flake graphite generally consists of bone and binder, bone evenly distributed in the binder phase. After roasting and graphitization, orthopedic and binder form graphite structures that are well bonded together and can generally be distinguished from orthopedic and binder by the distribution of pores.

Isotropic flake graphite is a kind of porous material. Porosity and pore structure have great influence on the properties of graphite. The higher the volume density of flake graphite, the smaller the porosity and the higher the strength. Different empty distribution will affect the radiation resistance and thermal stability of flake graphite. In industry, isotropy is generally used to evaluate the isotropy properties of graphite materials. Isotropy refers to the ratio of thermal expansion coefficients in two vertical directions.

Isotropic flake graphite has good thermal stability and excellent radiation resistance in addition to the electric and thermal conductivity of general graphite materials. Because its physical properties are the same or similar in all directions, isotropic flake graphite has a longer service life, and can greatly reduce the difficulty of design and construction. At present, anisotropic flake graphite is widely used in solar photovoltaic material manufacturing equipment, edM mold, high temperature gas cooled reactor core components, and continuous casting mold and other aspects.
