Silicates are converted to volatile SiF 4, which will be lost in open vessel digestion procedures. HF by itself is more effective in the digestion of silicate rock minerals than when mixed with another acid.
WitrynaThen, HF-based etchants (HF:NH4F) are applied to remove the subsurface impurity defects and the surface quality, impurity contents and laser damage resistance of etched silica surfaces are tested. The results indicate that the presence of impurity defects could induce a dramatic rise of local temperature and thermal stress.
