China's graphite industry has advanced from resource-based to technology-driven alongside industrial modernization. In the 1980s and 1990s, relying on abundant natural graphite resources, the industry focused on the primary processing of flake graphite and amorphous graphite, mainly used in basic fields like metallurgical refractories and pencil leads. Product purity was low, and added value limited. Since the turn of the century, the rise of high-end industries such as new energy and electronics, combined with stricter environmental policies, has driven the industry's transformation toward purification upgrades, synthetic alternatives, and functional modification. Natural graphite has achieved high purity through processes like flotation and alkali roasting. Synthetic graphite has developed rapidly due to controllable raw materials and stable performance. Meanwhile, new products like flexible graphite, expanded graphite, and graphene have been industrialized, achieving breakthroughs in sealing, thermal conductivity, and electrical conductivity applications.

In recent years, high-end demands for lithium-ion battery anodes, semiconductor thermal management, and nuclear reactor moderators have surged. Coupled with the evolution of standards (GB/T 10698 for expanded graphite, GB/T 3518 for flake graphite, GB/T 3521 for chemical analysis methods), the industry is accelerating its upgrade toward functional customization and high-end applications. Today, China is the world's largest producer and consumer of graphite, with products covering all categories: natural graphite, synthetic graphite, and fabricated graphite products, widely used in dozens of fields including new energy, metallurgy, electronics, and environmental protection.

We have set up a dedicated graphite materials testing team. Based on product type and application scenario (battery anodes, sealing materials, thermal components), we provide customized testing services—including purity analysis, mechanical properties, thermal conductivity, and electrochemical performance—helping products build advantages in performance optimization and technological innovation.
