Weakening of Soda‐Lime Glass by Particle Impact During Hydrofluoric Acid Etching

During etching of soda‐lime glass in hydrofluoric acid solutions, insoluble reaction products can collect in the acid solution or deposit on the glass surface. In this study it is shown that impact of these insoluble reaction products on the etching surfaces can cause strength degradation. The insoluble reaction products are characterized by scanning electron microscopy, wet chemical, X‐ray diffraction, and surface area analyses.
