Nichrome etchant

DescriptionNichrome etchant is a high purity etching system that is a mixture of ceric ammonium nitrate and nitric acid. It can be used to etch the nickel and chromium alloy.Ceric ammonium nitrate-based etchant. Etches Al, Cr, Cu, Ni, GaAs. Surface oxidizes Si, Ta/TaN. Etch rate of 50 Å/sec @ 40 °C. Etches cleanly with only a deionized water rinse needed.Nichrome etchant is used in the fabrication of microheater patterns of polydimethyl siloxane (PDMS), silica (SiO2) and glass substrates, which can be further used in the fabrication of flow sensors. It may also be used to etch out nickel (Ni) from the electroplated Ni on amorphous silica wafers.For use at room temperature or elevated temperature. Etches cleanly, eliminating need for an intermediate rinse.
