Silicon Metal
High-purity silicon metal for chemical, metallurgical, electronics, and solar energy industries. Available in multiple grades to meet diverse international requirements.
Product Overview
Silicon metal (industrial silicon) is produced by reducing quartz sand with carbon in an electric arc furnace. With purity ranging from 98.5% to 99.9%, it is an indispensable base material in modern industry.
Eastern Union operates two modern silicon metal smelting plants in South China with an annual capacity exceeding 60,000 tons. We adhere to international quality standards with standardized laboratories and advanced testing equipment.
