Frequently Asked Questions

Q: What are the primary applications of flake graphite powder?

Flake graphite powder is widely used as electrode materials, positive brushes, carbon rods, lubricating additives, battery absorbents, and in the production of refractory materials.

Q: What is the difference between natural and synthetic graphite?

Natural graphite is formed through geological processes of organic matter under high pressure and temperature, while synthetic graphite is man-made through chemical processing. Natural flake graphite is prized for its cost-effectiveness and inherent crystalline structure.

Q: Can the particle size and purity of the graphite be customized?

Yes, we offer carbon content from 70% to 99.99% and mesh sizes from 32 to 325. We can also produce super-fine powders between 5um and 38um based on user requirements.

Q: What makes expandable graphite unique?

Expandable graphite undergoes a special modification treatment allowing it to expand 100-350 times its original volume when exposed to high temperatures, making it ideal for fire retardants and oil absorption.

Q: How does flake graphite perform in corrosive environments?

Flake graphite is highly stable at room temperature and possesses excellent resistance to acids, alkalis, and various organic solvents, ensuring longevity in harsh chemical environments.

Q: What certifications do your manufacturing facilities hold?

Our factories have achieved ISO Certification and we hold 23 national patents for our specialized graphite processing technologies.
