Natural occurrence
Sodium hexafluorosilicate occurs naturally as the rare mineral malladrite found within some volcanic fumaroles.
Manufacturing
Sodium fluorosilicate is made by
neutralizing
A neutralizing antibody (NAb) is an antibody that defends a cell from a pathogen or infectious particle by neutralizing any effect it has biologically. Neutralization renders the particle no longer infectious or pathogenic.
