**Expanded Graphite (EG)** is a unique porous carbon material derived from natural flake graphite through processes including chemical intercalation, washing, drying, and high-temperature expansion. This transformation results in a lightweight, worm-like substance that retains the inherent advantages of natural graphite—such as temperature resistance, corrosion resistance, and self-lubrication—while gaining new properties like **compressibility, resilience, adsorption capacity, and environmental compatibility**. First developed in the 1970s primarily for sealing applications, EG has since unlocked a broad spectrum of industrial uses.

Refractory Industry Upgrade: Natural Flake Graphite as a Key Raw Material The global refractory industry is undergoing a major transformation as steel, glass, and non-ferrous metal producers demand materials with higher performance, longer service life, and greater environmental compliance. Among the raw materials driving this shift, natural flake graphite has become essential. Known for its outstanding thermal stability, high melting point, and oxidation resistance, graphite provides significant advantages in the production of refractory bricks, crucibles, and casting molds
