Under the spirit of adventure, challenge, and perseverance, OCI Materials has been developing advanced materials since its establishment in 1982. Actually, the present company name, OCI Materials, started to be used from 2004. In addition, from this time, OCI Materials began to take steps towards becoming a global advanced material corporation equipped with high technical skills and production capacity.

Korea has long been relying on imports of electronic materials. Keeping pace with the age of the development of the production of electronic materials, OCI Materials developed special abrasives (garnet, cerium), anode active materials (graphite) for secondary cells, and special gases such as NF3 (nitrogen trifluoride), WF6 (tungsten hexafluoride), and SiH4 (monosilane) for semiconductors, TFT-LCD, and solar cells.

As a result, OCI Materials is now acknowledged as a company that grew remarkably over the past 10 years. OCI Materials is now striving to settle its position with an increased market share of the global market based on accumulated capacity from the newly built 4th NF3 factory and the 2nd SiH4 factory. OCI Materials was also designated as a representative 'low carbon, green growth' company – the core project of the Korean government. Therefore, OCI Materials is exporting the basic material called SiH4 (monosilane). SiH4 is an essential material to produce solar cells – a growth engine of the next generation.
