And there's even more. Consider, for example, agrochemicals, where about 17% of active materials used as pesticides and fungicides are based on fluorinated compounds. The manufacture of silicon chips relies on the wet and dry etch processes utilizing materials such as ultra-high-purity HF and NF3. Elemental fluorine is used to prepare UF6, used by the nuclear industry for uranium enrichment. Electrical utilities rely on the high dielectric strength of SF6, also manufactured using direct elemental fluorination, for high-voltage circuit breakers and transformers. And within the chemical processing industries, catalysts include BF3 and SbF5, KF is used as a fluorinating agent, and AlF3 is used to process aluminum.
