Within the Types segment, large‑diameter graphite electrodes are classified chiefly into High‑Purity and Low‑Purity grades, each reflecting divergent cost structures and performance envelopes. High‑Purity electrodes, comprising approximately 55% of the market, exhibit minimal impurity levels, delivering enhanced arc stability and longer service life, which is critical for high‑throughput EAFs. Conversely, Low‑Purity electrodes make up the remaining 45%; they are priced lower but display higher wear rates, making them suitable for secondary or less demanding furnace operations. A secondary distinction arises from the manufacturing process—sintered versus baked electrodes—where sintered products dominate the high‑purity share due to superior density, while baked electrodes are prevalent in the low‑purity cohort. This taxonomy clarifies how type selection directly influences capital expenditure and operational efficiency, thereby shaping the overall market dynamics for large‑diameter graphite electrodes.
