PROCESS OF SILICON TETRAFLUORIDE GAS SYNTHESIS

A process of producing silicon tetrafluoride from fluoride containing feedstocks. The process calcines the fluoride containing feedstock and a silica containing feedstock before reacting the mixture with sulfuric acid to produce silicon tetrafluoride. The silicon tetrafluoride is scrubbed with sulfu...

Zusammenfassung:A process of producing silicon tetrafluoride from fluoride containing feedstocks. The process calcines the fluoride containing feedstock and a silica containing feedstock before reacting the mixture with sulfuric acid to produce silicon tetrafluoride. The silicon tetrafluoride is scrubbed with sulfuric acid. Excess sulfuric acid is recycled to the process. The process demonstrates an economic and environmentally friendly way to produce high quality silicon tetrafluoride.
