What materials are resistant to the Piranha solution?

Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2). The result of the mixture gives rise to a strong union of two acids called per-hexa-sulfuric acid (H4SO6) that is used to clean organic residues off substrates. Because the mixture is a strong oxidizing … See more Many different mixture ratios are commonly used, and all are called piranha. A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; other protocols may use … See more Piranha solution is used frequently in the microelectronics industry, e.g. to clean photoresist or organic material residue from See more Piranha solution is dangerous to handle, being both strongly acidic and a strong oxidizer. Solution that is no longer being used should never be left unattended if hot. It should never be stored in a closed receptacle because of the risk of gas overpressure and See more • How to make Piranha Solution on YouTube (responsibly) • How to real etching in plated copper: H2SO4 + H2O2 + Cu on YouTube See more The effectiveness of piranha solution in decomposing organic residues is due to two distinct processes operating at noticeably different rates. The first and faster process is the removal of hydrogen and oxygen as units of water by the concentrated … See more • Aqua regia (HNO3 + 3 HCl) • Fenton's reagent (H2O2 + Fe ) • Green death (xH2SO4 + yHCl + zFeCl3 + wCuCl2) • Peroxydisulfuric acid, or Marshall's acid (H2S2O8) See more WebPiranha solutions are used to remove organic residues from substrates, particularly in microfabrication labs. The traditional piranha solution is a 3:1 mixture of sulfuric acid and 30% hydrogen peroxide. The solution may be mixed before application or directly applied to the material, applying the sulfuric acid, followed by the peroxide. ...
