Research into fluoride compounds, started by a team led by Dr. Yung Ok AHN under the guidance of Dr. Park Dal-jo in the early 1970s, purported to develop new chemical processes and improve capacity in factory design. The CFC-12 manufacturing technology, whose pilot tests were completed at KIST, was transferred to industry by K-TAC. At the start of the 1980s, a team led by Dr. Geon Yu PARK and Yeong Su GWON in the Chemical Industry Department and supported by the Ulsan Chemical Co., Ltd. succeeded in developing and commercializing CFC-11/12, AHF, and HCFC-22/141b. Following the resolution of the UN to preserve the ozone layer, the team began to search for materials to replace CFC and developed HFC-134a and HFC-32/125. It also developed an electrolytic preparation method for fluoride, the technology transfer of which was restricted worldwide, and more electronic materials such as NF3, LiPF6, and FC-116/318, currently in the process of commercialization. The team has maintained its company partnership for over 33 years--- a record at KIST. It carried out two research projects with the company in 2005. The money saved from reduced imports of fluoride compounds is estimated at 700 billion won.
