At the heart of the electronics revolution stands the silicon chip and the microprocessor. The manufacture of these wafers requires the use of ultra-pure chemicals for the etching and cleaning operations.  And electrical power plants depend on Solvay insulants. 

Manufacture of semiconductors
The clean room manufacture and wet-bench fabrication of semiconductors rely on high precision etching. Ultra pure etching and cleaning chemicals from Solvay match such stringent conditions. 

Electrical insulation
Sulfur hexafluoride provides excellent quenching and insulating properties in power plants and substations.
