Paper Abstract

In order to study the mist phenomenon on phosphate glass, the chemical composition of the hydrolysis layer on the glass surface of phosphate glass was investigated. The solid and liquid components of the used slurry and the surface composition of polished phosphate glass were tested. The experimental results show that the SIMS test results show that the content of K does not change with depth, and the content of Mg, Al, Nd firstly increases with depth and then tends to be gentle; K element does not participate in chemical reactions during polishing, just simply mechanical removed; but Mg, Al, and Nd elements are not only mechanically removed but also participate in chemical reactions and are precipitated as ions, which is consistent with the XRF test results. It is proposed a new substance generated on the surface of phosphate glass during polishing process, a hydrolysis layer formation model was proposed. The mist phenomenon is related to the hydrolysis layer, which is different from the substrate material and properties (density, light reflectance, etc.). So different scattered light is seen and the thicker the hydrolyzed layer, the stronger the scattered light. Moreover, the severity of mist is related to the thickness of the mist layer, and the thicker the thickness, the more severe the mist.
