Frequently Asked Questions

Q: What is the primary difference between Natural and Synthetic graphite?

Natural graphite is formed by geological processes under high temperature and pressure, while synthetic graphite is man-made. Natural flake graphite is preferred for its cost-effectiveness and inherent layered crystalline structure.

Q: How does the particle size (mesh) affect the lubrication properties?

Generally, the larger the graphite flake, the lower the coefficient of friction, which leads to better lubrication performance in industrial applications.

Q: Can you customize the carbon content for specific battery requirements?

Yes, we offer a wide range of carbon contents from 70% to 99.99%. Our technicians can adjust the purity levels to meet your exact electrode or battery specifications.

Q: What makes "Expandable Graphite" different from regular flake graphite?

Expandable graphite undergoes special modification treatment. When exposed to high temperatures, it expands up to 100-350 times its original volume, making it ideal for fire retardants and absorbents.

Q: Is this graphite powder suitable for refractory materials?

Absolutely. Due to its extremely high melting point (3850℃) and low thermal expansion coefficient, it is a primary choice for high-temperature refractory additives.

Q: What certifications do your manufacturing facilities hold?

Our factories are ISO Certified, and we hold 23 national patents for our graphite processing and modification technologies, ensuring global quality standards.
