In the laboratory, the compound is prepared by heating BaSiF₆ >300 °C, whereupon the solid releases volatile SiF₄, leaving a residue of BaF₂.

Occurrence Vulcanic plumes contain significant amounts of silicon tetrafluoride, the daily production can reach several tonns per day. The silicon tetrafluoride is partly hydrolysed and forms hexafluorosilicic acid.
