Nitric acid and sulfuric acid and solar glass

Can nitric acid etch glass?

Especially, boiling the glass in a 70% nitric acid solution for 30 min is more effective in the reduction of sodium, calcium, and aluminum atoms at the surface of the glass than other etching methods with nitric acid. The surface morphologies of the glasses were very similar regardless of the chemical etching treatments with nitric acid etchant.

Does nitric acid etching affect surface morphology?

The surface morphologies of the glasses were very similar regardless of the chemical etching treatments with nitric acid etchant. Root-mean-square surface roughness of the bare glass was 0.58 nm but that of the glass etched with nitric acid was ranged from 5.4 to 6.8 nm.

How does annealing temperature affect nitric acid etching?

Sodium, aluminum, and calcium at the surface of the glass increased with an annealing temperature regardless of chemical etching with nitric acid, but the Na, Al, and Ca content at the surface of the glass boiled in 70% HNO 3 for 30 min was greatly reduced relative to that of the surface of the bare glass at an annealing temperature of 500 °C. 1.

Can sulfuric acid dissolve glass?

Sulfuric acid, H2SO4, is not able to dissolve glass, which is why it can be safely stored in a glass container. This is because sulfuric acid is simply not corrosive enough to eat through the extremely strong silicon dioxide (SiO2) bonds that are the main component found in glass.
