With increasing microhardness of the surface layer the rate of polishing
decreases proportionately . These results show that the hydrated gel layer is
worn away in polishing ; the formation and density of the gel layer depend
decisively on the ...

The dominant reaction step is the partial leaching of glass components with the
formation of a gel - like layer of network formers . The third type is characterized
by the formation of a one - or multicomponent protective layer from components
of ...

Whereas the acetic acid leached the Pb2 + ions by a diffusion - controlled
process , the SiO2 network of the gel layer formed was decomposed by the NH
HF2 and Na2CO3 solutions , except in the early and final phases , at
approximately ...
