Stability and reactivity

Stable under normal conditions, but hydrolysable in aqueous solution. Do not use at temperatures higher than 620ºC due to decomposition.
Avoid temperatures higher than 390ºC. Avoid contact with water, acids, oxidising agents, cyanides. active metals,s uch as Al or Mg. Not soluble in organic solvents. Dissociation reaction provides hexafluorosilicate as product, which hydrolyses providing fluoride and release of HF being possible. At temperatures higher than 390ºC, SiF4 and NaF are formed.

Disposal considerations

Dispose waste according to local/regional/national regulations.
Containers should be carefully cleaned before disposal.
