Feature of graphite
- High temperature resistance: Graphite is one of the currently known
highest-temperature resistance materials. Its melting point is 3850
° C ± 50 ° C, boiling point up to 4250 ° C. Under 7000 ° C
ultra-high temperature electric arc, the loss of graphite is
minimum, 0.8% of the total weight in 10 seconds, Thus, the high
temperature resistance of graphite is very prominent.
- Excellent thermal shock resistance: Graphite has good thermal shock
resistance, when the temperature changes suddenly, the crack will
not emerge due to the small thermal expansion coefficient
- Thermal and electric conductivity: Graphite has good thermal
conductivity and electrical conductivity. Compared with the general
material, its thermal and electrical conductivity is very high.
Four times higher than stainless steel, two times higher than
carbon steel and 100 times higher than the average non-metallic.
- Lubricant: The lubricating properties of the graphite is similar to
MoS2, the friction coefficient is less than 0.1. Its lubricating
properties changes from the size the graphite flake ,the bigger the
flake is , the smaller the coefficient is ,and the lubricant
property will be better.
- Chemical stability: Graphite has good chemical stability at room
temperature. Resistance to acid, alkali, and organic solvents.
The use of graphite
With the above excellent property ,the graphite is widely used in
metallurgy, mechanical, electrical, chemical, textile, defense and
other industries. Below is the classification.
