Embodiment 1
[0043] This embodiment provides a glass etching method, the glass etching method comprising the following steps:
[0044]Under the ultrasonic conditions of 75°C and 200kHz frequency, the sodium glass is etched with an etching solution; the etching solution contains ethanol with a volume concentration of 20%, and sodium hydroxide with a mass concentration of 38% in water.
[0045] The glass surface roughness test chart after the present embodiment etching is as figure 1 shown, from figure 1 It can be seen from the figure that the etched glass surface is relatively smooth and the roughness is small.
Embodiment 2
[0047] This embodiment provides a glass etching method, which is the same as that of Embodiment 1 except that the etching solution contains ethanol with a volume concentration of 5%.
Embodiment 3
[0049] This embodiment provides a glass etching method, which is the same as that of Embodiment 1 except that the etching solution contains ethanol with a volume concentration of 10%.
