H3PO4:H2O2:H2O is a corrosive (it can burn your flesh, eyes, lungs, and mucous membranes) and oxidizing (it can set things on fire) liquid. It contains Phosphoric Acid (H3PO4), Hydrogen Peroxide (H2O2), and

1990年10月20日 · This paper deals with the chemical etching of (100) InP using a phosphoric acid and hydrogen peroxide mixture. It is shown that the etching rate is strongly dependent on the relative...

1987年3月1日 · SEM observations are reported with the aim of studying the etching characteristics of GaAs substrates in H 3 PO 4:H 2 O 2:H 2 O systems. The surface morphology is shown to vary extensively with the etchant composition and etching time.

2024年11月19日 · Transene's Chemical Compatibility Chart provides a useful quick-reference for which Transene etchants attack which materials. As a side-note, Transene provides many pre-mixed solutions that you can order, saving you the time and uncertainty of measuring/mixing such chemicals yourself.

2020年7月7日 · The all-organic photosystem with H3PO4 as a stabilizer may provide a basis of photocatalytic H2O2 splitting. While H2 can serve as a renewable fuel, its large scale production, storage, and ...

1990年10月1日 · This paper deals with the chemical etching of (100) InP using a phosphoric acid and hydrogen peroxide mixture. It is shown that the etching rate is strongly dependent on the relative concentration of the two species; it is maximal for an equivolumic solution, and depending on the dilution it ranges from 70 to 20 Å/min.

图 3 描绘了 InGaP 与 HCl:H3PO4:H2O2 (1:10:1) 的蚀刻速率与温度的关系。 温度从 20°C 增加到 44°C 导致蚀刻速率增加约三倍。

The HC1:H3PO4:H2O2 etchant is a nonaqueous solution of HCl and H202 in the H3PO4 solvent. H2O2, which is the oxidizing agent, plays a very important role. Hydrochloric acid alone, without H2O2, does not attack GaAs. However, it removes natural oxides from the GaAs surface. On the other hand, HCl has long been used as an etchant for InP.

2021年12月8日 · The reaction I am aiming to achieve is the conversion of copper to cupric chloride (Cu (II)Cl2), in a HCl and H2O2 solution. The end product will be stored, as CuCl2 is also a good etchant, and converts into Copper I Chloride when used as such.
