Within the Types segmentation, Graphite Electrode Billets are classified primarily into natural graphite and synthetic graphite variants. Natural graphite billets, derived from mined flake or amorphous sources, dominate the market due to lower raw material costs and established supply chains, contributing approximately 55 % of total volume. Synthetic graphite billets, produced through high‑temperature treatment of petroleum coke, command a premium for superior purity and isotropic properties, capturing roughly 35 % of the market, especially in high‑end steel and specialty alloy applications. A niche segment of blended billets—combining natural and synthetic feedstocks—accounts for the remaining 10 %, offering a balance of performance and cost. The relative weight of each type is driven by factors such as furnace technology, product specifications, and price sensitivity, forming a critical component of the overall market taxonomy.
