- Production Process
P4(yellow phosphorus) is combusted and undergoes hydration and refinement to produce Phosphoric Acid (75%, 85%). Additional refinement is executed to produce high-purity Phosphoric Acid for semiconductors.. OCI started production of Phosphoric Acid (H3PO4) at the Incheon Plant in 1980, and LCD-grade Phosphoric Acid production started at the Gunsan Plant in 2003. OCI started supplying high-purity Phosphoric Acid to Samsung Electronics in 2008, and expanded supply to the world's leading semiconductor companies.
