Hi,

I want to remove SiO2 layer which occurs naturally on the Si3N4 powders. But I do not want to use HF because it is not safe. Is it possible to remove SiO2 by using any other acids/bases?
Any information is appreciated. Thanks for all.

As far as I can remember, HF is pretty much it for liquid etchants. Plasma etching might be another avenue.
